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 ...

Standard atomic weights, those numbers emblazoned under the elements on the periodic table, were once thought of as unchanging constants of nature. But researchers have tweaked the atomic weights of ...

In a groundbreaking development, researchers have unveiled a revolutionary AI-driven periodic table that’s set to transform the landscape of modern ...

The iconic chart of elements has served chemistry well for 150 years. But it’s not the only option out there, and scientists are pushing its limits. By Siobhan Roberts When Sir Martyn Poliakoff, a ...

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 ...

Nineteen elements on the periodic table — including gold, cadmium, arsenic and aluminum — are getting their atomic weights adjusted. The International Union of Pure and Applied Chemistry (IUPAC) ...

A team of Russian and American scientists announced today the creation of several atoms of the previously unknown element 117. The discovery of “ununseptium” will eventually fill a longtime gap on the ...
