The periodic table, also called the periodic table of elements, is an organized arrangement of the 118 known chemical elements. The chemical elements are arranged from left to right and top to bottom ...

For starters, elements 114 and 116 don't occur in nature. So don't look for them in your backyard. That's because they were made in a lab. Which may seem like cheating, but that's how it's done these ...

Cal: OK, friends. Chemistry time and in the studio with me I have super science school teacher Mrs Roberts, who's gonna show us how to make a massive fizzing volcano. We're gonna have sparks, lava ...

It’s not every day an element gets added to the periodic table. The last time it happened was 2016, when four new elements became official. For these elements, reaching the table was an epic quest ...

The periodic table of elements is one of the most significant tools in science, organizing all known chemical elements in a structured and meaningful way. It helps scientists understand element ...

Mankind has known materials such as gold, silver, mercury, iron, phosphorous, sulphur and others since antiquity. Alchemists tried making gold out of “base” metals — with no success. But we had to ...

This year is the International Year of the Periodic Table of Chemical Elements—and today (March 6), the modern version celebrates its 150 th birthday. To find out more about the table and how new ...

Scientists proposed a new sequence by assigning a Mendeleev Number (MN) to each element The elements are arranged in the new table solely based on their electronegativity and radius The researchers ...

It says something about Dmitri Mendeleev that he had an easier time keeping track of the number of protons in the nucleus of an atom than the number of brothers and sisters living under his roof. The ...

Kids have to memorize four new elements, now that the powers that be in the world of chemistry have expanded the periodic table. The International Union of Pure and Applied Chemistry has accepted the ...

Everybody remembers trying to learn the periodic table in science lessons at school. The table is one of the fundamental building blocks of chemistry, explaining the relationship between different ...

Science Classrooms Across the Nation (WHTM) — February 7 is National Periodic Table Day, when we celebrate the efforts of scientists over the centuries to figure out how different elements are related ...
