The modern periodic table

The Periodic Table of the Elements was probably a dreary chart on your classroom wall when you were a child. Unfortunately, for many people, the periodic table is the thing they were forced to memorise as youngsters. But the fact is that this small table is a must-have for scientists all over the world. The periodic table has a few fun, interesting, and little-known facts written equally with science enthusiasts and any students studying chemistry in mind.

Scientists preferred battery elements to weigh the elements

The scientist working with the element

Scientists passed currents through multiple solutions to split them up into the atoms of particular elements in order to calculate the weight of each of the 63 known elements at the time.

Batteries were used to distinguish the atoms because their polarity caused atoms of one element to move in one direction while those of another moved in the opposite direction. The atoms were then separated and measured in different containers.

To measure the weight of each of the 63 known elements at the time, scientists moved currents through various solutions to break them up into the atoms of specific elements.

Since the polarity of batteries caused atoms of one element to move in one direction while those of another moved in the opposite direction, they were used to separate the atoms. After that, the atoms were divided.

The periodic table might not be able to extend to 137 elements

The physicist Richard Feynman predicted that if the 137th factor exists, we would never be able to see it.

This is partially due to the fact that the electrons of element 137 will orbit at the speed of light in theory. In theory, the electrons of element 139 will orbit faster than the speed of light, making it difficult to achieve given current scientific knowledge.

Opposites always attract

opposite elements are combined and made a structure

The groups that “kiss” are the ones that can be stably fused together if you take the modern periodic table, cut out the complicated middle columns, and fold it once down the middle of the Group 4 elements.

These elements have complementary electron structures, allowing them to be mixed together. It’s so lovely..isn’t it.

Some elements are more understandable in the Greek language

elements with their scientific names

Then there are the elements that are named after the Greek word that best describes their characteristics. The word “argon” comes from the Greek word “Argos,” which means “lazy” or “idle.” Bromine, which has an unpleasant odour, is named after the Greek word “bromos,” which means “stench.”

Some of the elements named after famous Scientists, Planets or Mythological Figures

The great scientist Albert Einstien

Albert Einstein was given the name Einsteinium, while germanium, americium, and gallium were given the names of the sites where they were discovered. Uranium was named shortly after Uranus was discovered.

Some of the elements have mythological names. Thorium, for example, is named after Thor, the Scandinavian god of thunder. Titanium, on the other hand, is named after the Greek gods of war.

Technetium

Einsteinium was named after Albert Einstein, while germanium, americium, and gallium were named after the locations where they were found. Uranium was named after the planet Uranus, which was discovered soon after.

The names of some of the elements are mythological. Thorium, for instance, is named after Thor, the Scandinavian thunder god. On the other side, titanium is named after the Greek gods of battle.

It was used to correctly predict elements that hadn’t been discovered

Clear Light Bulb Placed on Chalkboard

There were some open spaces in Mendeleyev’s original periodic table when he placed it together. Mendeleyev was able to correctly predict the discovery of a few elements by estimating their properties in relation to other elements near the table’s spaces. Before they were found, he correctly estimated the weights and chemical actions of gallium, scandium, and germanium.

And that’s all about today’s article. Hope you enjoyed knowing these facts about the periodic table which was never been told in our boring science classes. LOL!

Top 10 Richest Countries over the Globe 2021

Qatar 1
Qatar, Richest Country in the World

What are the top 10 richest countries in the world? Qatar has consistently come out on top of the list in recent years. For many of us, this question almost automatically brings to mind economic powerhouses such as the United States and China. This may be true if one is to use the gross domestic product (GDP) as the basis for measuring national wealth. However, size is of no consequence, and national revenue no longer a reliable basis by which to classify whether a country is rich or poor.

Experts have found that a far more accurate alternative is to look at each nation’s data on GDP per capita based on purchasing power parity. To put it simply, a country’s wealth should be measured by the totality of all goods and services (excluding revenue and investments from overseas), taking into account a country’s population. So in the case of Qatar, which remains the richest country in the world today, its GDP per capita of $129,360 represents the annual income of the average Qatari.

The International Monetary Fund (IMF) is known for issuing biannual reports on the economic performance of the world’s richest nations based on their GDP per capita. It likewise makes use of PPP capita as an additional basis for its report. Essentially, PPP makes a just comparison of living conditions among different countries by taking into consideration inflation rates and the relative cost of living.

Traditional economic powers have ceased to become the wealthiest nations in the world. Although GDPs have been increasing at breakneck speed, the distribution of wealth has yet to undergo radical changes. Here, we list the top 10 richest countries in the world.

Hong-Kong –

Hong-Kong

Hong-Kong

This former colony of Great Britain is now a special administrative region of China, which begs the question: is it an independent country? This is apparently the case as the whole world in general treats it as one. It is one of Asia’s financial hubs, ranking no. 4 out of the world’s 190 economies in the Ease of Doing Business index that the World Bank periodically compiles. A popular destination for startups, Hong Kong is open to foreigners owning 100% of their businesses despite the absence of citizenship. It is also home to the largest number of ultra-high net worth ($30 million at the least) people in the world.

Kuwait –

Kuwait

Kuwait

Ninth in our top 10 richest countries in the world list, this small Arab nation is known for having a petroleum-based economy with petroleum-based products accounting for 95 percent of its exports. It, therefore, does not come as a surprise that Kuwait’s GDP per capita has reached $66,980, spiking by 1.9 percent from the previous year. The country is not only the ninth richest in the world, but is also one of the wealthiest among Gulf Cooperation Council member states, second only to Qatar. But the fact that the country sits on around 10 percent of the world’s petroleum reserves has not kept it from exploring other revenue sources. In fact, it has been seeking to diversify into other potential income sources in preparation for the future.

the United Arab Emirates (UAE) –

the United Arab Emirates (UAE)

the United Arab Emirates (UAE)

Another Middle Eastern country that relies heavily on petroleum revenues, the United Arab Emirates (UAE) also benefits from income derived from its telecommunications and services sectors. It does not rest on its laurels despite being among the world’s most wealthy nations. It has been diversifying its income sources, betting on industries that have high-yield potential. This move has immensely benefited the national economy, with the tourist trade helping the economy through the 2007-2009 world financial crisis. Sound economic policy has indeed been sustaining the UAE, resulting in a 2.4 percent increase in its GDP per capita, which now stands at $70,262.

Norway –

Norway

Norway

A prominent country in Scandinavia, Norway is gifted with both beauty and charm, not to mention a rich economy. In fact, its GDP per capita has expanded by 3.1 percent in 2018, reaching a staggering $74,318. Industrialization has greatly contributed to the country’s economic growth, with activities such as natural resources and petroleum exploration, and fishing contributing in bulk to the economy. Known for its impeccable living standards, Norway’s monetary policy is of an independent nature, which has apparently been working to its advantage given its high productivity, state-sponsored healthcare, and negligible unemployment rate.

Ireland –

Ireland

Ireland

The land is known for weaning great writers and its lovely tourist spots, Ireland has evolved into one of the most affluent nations in the world. It has one of the highest living standards worldwide thanks to its robust economy, which is primarily driven by trade and investment specifically. Ireland’s GDP per capita has increased by 6.1 percent, reaching $77.670. Despite peaking in 2008, Ireland’s economic growth remains the envy of other countries. The entry of foreign investors like Microsoft, Google, and Apple has transformed the country into an exporter of medical, electrical, and computer equipment. Also contributing to its economic growth are its pharmaceutical and chemical industries, along with natural resources such as fisheries, minerals, and timber.

Brunei Darussalam –

Brunei Darussalam

Brunei Darussalam

This small Southeast Asian nation is populated by only 400,000 people. But don’t let its size fool you. Brunei Darussalam has consistently made it to the top 10 richest countries in the world in recent years. This year, the country holds the no. 5 spots with a GDP per capita of $81,612, up 3.1 percent from 2017. This robust Southeast Asian economy is heavily dependent on its oil and natural gas production, which supports more than half of its GDP. This is further reinforced with income from its investments overseas and local production. Brunei, however, is starting to diversify its economy by investing in other sectors. The strong economy is reflected in the government’s subsidy of food and housing and the provision of free healthcare to its people.

Singapore –

Singapore

Singapore

This cosmopolitan city-state of 5.612 million people is known as the wealthiest nation in Asia and by far, fourth in the whole world with a GDP per capita of $98, 255, a 4.4 percent increase from 2017. Despite its minuscule size, lack of natural resources, and agricultural land, it has managed to amass wealth that other countries only dream of. Today, Singapore’s economy continues to grow, driven primarily by foreign investments and trade. The largest economic sectors include banking, shipbuilding, and electronics. Dubbed as the most expensive country in the world, Singapore has been living up to its reputation as its economy expanded by 3.9 percent during the second quarter of 2018 alone. Much of this has been attributed to the country’s liberal economic policy and multicultural economy. Although the financial services sector remains the backbone of the country’s economy, its services and manufacturing industries have consistently contributed to its economic standing.

Luxembourg –

Luxembourg

Luxembourg

This small European nation is known for its majestic castles, delectable cuisines, and being the last Grand Duchy in the world. But the country more than makes up for its size with its strong economy. Luxembourg ranks third in our list of the top 10 richest countries in the world. The country has posted a GDP per capita of $109, 199, an increase of 3.9 percent from last year. Its diverse natural resources are seen as the main driver of Luxembourg’s economic growth with the steel, industrial, and banking segments as its leading revenue generators. It has also been attracting banks from around the globe owing to its low taxes, proof of which is the fact that the country has over 150 banks. Conservative economic policies have also played a role in the country’s economic growth with an economy known for innovation and negligible inflation rates.

Macau –

Macau

Macau

This former Portuguese colony has established itself as the second wealthiest nation in the world, posting a 7.4 percent increase in its GDP per capita, which has reached $118.099. Its strong economy is driven primarily by tourism and gambling, earning the title “largest gambling center in the world.” Compared to other gambling economies, Macau has reaped the most benefit from the sector, continuously posting the highest gambling revenue in the world since the year 2006. Visitor arrivals have likewise increased, rising by 8 percent to 16.81 million during the first six months of 2018.  Although these income sources have been consistently delivering, moves to develop the administrative and manufacturing sectors are underway.

Qatar –

Qatar

Qatar

Ranking first in our Top 10 richest countries in the world list is oil-rich Qatar. Its robust economy, which has been outperforming the rest of the world, is powered by its well-established petroleum sector, which accounts for around 85 percent of its export and 70 percent of total national revenue. With a population of only around 2.639 million, Qatar enjoys the economic benefits of a small nation blessed with vast oil reserves. The country, in recent years, has enjoyed surplus revenues from the oil sector. Aside from this, the tourist trade has also been contributing to the national coffers, along with its steel and fertilizer exports. But Qatar’s economy is far from perfect, relying on ex-pat labor to keep its economic engine running. The government does not levy any taxes on Qataris, making them enjoy their earnings in full, along with the national health insurance that the government sponsors

Top 10 Desert
Top 10 Desert in the World

Deserts cover more than one-fifth of the Earth‘s land area, and they are found on every continent. A place that receives less than 10 inches (25 centimeters) of rain per year is considered a desert. Deserts are part of a wider class of regions called drylands. … Only about 20 percent of deserts are covered by sand.

desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to the processes of denudation.

Taklamakan Desert – Central Asia

Taklamakan Desert – Central Asia

Taklamakan Desert – Central Asia

The second-largest shifting-sand desert in the world, China’s Taklamakan Desert covers an area of 130,000 square miles (337,000 square kilometers). The desert is an incredibly harsh environment with lows going well below zero degrees in the winter, and water sources are almost nonexistent, making the area almost devoid of flora and fauna. Even those on the Silk Road tried to avoid the area by traveling on the fringes of the desert.

Tabernas Desert – Spain

The Mojave Desert covers portions of southeastern California and southern Nevada, along with small sections of northwestern Arizona and southwestern Utah. This desert is identifiable by the protected Joshua trees and is considered a ‘high desert.’ However, the incredible Death Valley, which is within the Mojave, is actually 282 feet (86 meters) below sea level. The Mojave is also home to the stunning Valley of Fire State Park plus many towns and museums, making it a very popular tourist destination.

Gobi Desert – China/Mongolia

The Gobi Desert is a beast of a desert spread across parts of southern Mongolia and northwestern China. It is famous for its role in the Mongol Empire and important stops along the Silk Road. The Gobi is also known for its extreme temperatures from as high as 122 degrees Fahrenheit (50 degrees Celsius) in the summer and extremely low temperatures in the winter. The area is also rich in fossils, including dinosaur eggs, and animals like Bactrian camels, Siberian ibex, and Gobi brown bears.

Atacama Desert – South America

Situated west of the Andes along the Pacific coast in Peru and Chile, the Atacama Desert is known as the ‘driest place on Earth’. Parts of the desert have never seen a drop of rain since records have been kept. This fact might lead you to believe that this area is devoid of life, but that’s not true. More than a million people call this desert home. Due to its location along the coast, the Atacama is cooler than most deserts and is frequently covered with fog.

Namib Desert – Africa

Covering most of Northern Africa – 3.6 million square miles – the Sahara Desert is the third largest desert on the planet and the largest hot desert. While many people often think of the gorgeous sand dunes that are found in the Sahara, they only comprise a small portion. The landscape is primarily made of rocky hamada, or barren land with rocky plateaus. You’ll also find small patches of grassland (albeit sparse), shrubs of the desert variety, mountains, and salt flats. The Sahara is also home to an impressive array of flora and fauna, including several species of foxes.

Coronavirus

A virus. Just a term for something that has the potential to completely ruin a normal life. Viruses are one of the deadliest things in this world. So here is the list of the top 10 deadliest viruses to shook and scare you. We must learn from these previous pandemics and viruses and try to be more prepared than ever while taking care of ourselves and our loved ones.

Marburg virus

Marburg_virus

The mortality rate in the first outbreak was 25%, but it was more than 80% in the 1998-2000 outbreak in the Democratic Republic of Congo, as well as in the 2005 outbreak in Angola, according to the World Health Organization (WHO).

The Black Death

The Black Death

The plague changed the course of Europe’s history. With so many dead, labor became harder to find, bringing about better pay for workers and the end of Europe’s system of serfdom. Studies suggest that surviving workers had better access to meat and higher-quality bread. The lack of cheap labor may also have contributed to technological innovation.

Rabies

Rabies

Although rabies vaccines for pets, which were introduced in the 1920s, have helped make the disease exceedingly rare in the developed world, this condition remains a serious problem in India and parts of Africa.

Smallpox

Smallpox

Mortality rates were far higher in populations outside of Europe, where people had little contact with the virus before visitors brought it to their regions.  For example, historians estimate 90% of the native population of the Americas died from smallpox introduced by European explorers. In the 20th century alone, smallpox killed 300 million people.

Dengue

Dengue

Dengue sickens 50 to 100 million people a year, according to WHO. Although the mortality rate for dengue fever is lower than some other viruses, at 2.5%, the virus can cause an Ebola-like disease called dengue hemorrhagic fever, and that condition has a mortality rate of 20% if left untreated. “We really need to think more about the dengue virus because it is a real threat to us,” Muhlberger said.

Influenza

Infuenza

The most deadly flu pandemic, sometimes called the Spanish flu, began in 1918 and sickened up to 40% of the world’s population, killing an estimated 50 million people.

Rotavirus

Rotavirus

Although children in the developed world rarely die from rotavirus infection, the disease is a killer in the developing world, where rehydration treatments are not widely available.

Ebola virus

Ebola

The first known Ebola outbreaks in humans struck simultaneously in the Republic of Sudan and the Democratic Republic of Congo in 1976. Ebola is spread through contact with blood or other body fluids, or tissue from infected people or animals. The known strains vary dramatically in their deadliness, Elke Muhlberger, an Ebola virus expert and associate professor of microbiology at Boston University, told Live Science.

HIV

HIV

An estimated 32 million people have died from HIV since the disease was first recognized in the early 1980s. “The infectious disease that takes the biggest toll on mankind right now is HIV,” Adalja said.

Coronavirus (Covid-19)

Coronavirus

The coronavirus outbreak came to light on December 31, 2019, when China informed the World Health Organisation of a cluster of cases of pneumonia of an unknown cause in Wuhan City in Hubei Province. Subsequently, the disease spread to more Provinces in China, and the rest of the world. The WHO has now declared it a pandemic. The virus has been named SARS-CoV-2 and the disease is now called COVID-19.

So this was the list of the top 10 deadliest viruses of all time. If you liked these then also check more amazing lists by clicking here.

Top 10 Fastest Trains in The World 2020.

In 2021, there are negligible trains are running due to pandemic.  What is the maximum speed for trains? In 2015, the Japanese maglev train L0 Series achieved an absolute railway speed record of 375 mph (602 km/h). In reality, there are about 10 super-fast trains with a speed greater than 200 mph. In this comparative review, we have collected such fastest trains in the world. You will find out what are the fastest trains in the world, what are their maximum speeds, in which countries they operate, who their manufacturer is and a lot of other interesting information.

In the post-war years when the baby boomers were kids, the word “train” used to evoke different images. These were images of colossal lumbering beasts such as the Flying Scotsman and Union Pacific Big Boy with six feet tall cast iron wheels and huge pistons heaving to and fro. From 1964 that all changed. The first “bullet train”, formally known as Shinkansen, ran in 1964 between Tokyo and Osaka. Ever since, the world has viewed railways differently.

Patentes Talgo, a Spanish company, developed Talgo 350 (T350). This very high-speed train entered the service with the name RENFE AVE Class 102. Besides, it started its journey on the Madrid-Barcelona and Madrid-Valladolid lines in Spain. The train is also known as Pato as its nose resembles the beak of a duck.

Spain commenced the trial runs of the entirely constructed prototype in 2002. Additionally, the designers designed the T350 train to be optimally aerodynamic to handle air pressure and air currents at high speeds. Its main feature is the high redundancy level in traction between rail and auxiliary systems. Moreover, it has a lightweight, airtight, and pressurized car body to comfortably pass through tunnels and crossings.

Besides, this train operates with the highest speed of 186 mph on Italy’s different high-speed lines. However, the AGV can run up to 224 mph. AGV trains consist of a fewer number of bogies per train that reduce the maintenance costs.

We can find more space inside of this high-speed train because it uses permanent-magnet synchronous motors. Additionally, the passengers of AVG Italo trains can travel between Rome and Naples in just an hour. Moreover, the trail follows the European TSI interoperability standard, which offers safety, reliability and environmental protection, availability, health, and technical compatibility.
