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 ...

When you see the periodic table, what comes to mind? The pieces on a Scrabble board? Maybe you think about your high school chemistry class. Maybe you think of the colorful table plastered on the wall ...

In their momentary life span, atoms of lawrencium, element 103, may have left a lasting impression on the structure of the periodic table. For the first time, researchers have measured a basic ...

The periodic table is used in chemistry to organize different elements. Elements are atoms with a different number of protons and electrons. Protons are particles that are in center of the atom and ...

Researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. The findings could lead to much cheaper materials ...

Researchers have developed a technique for generating atom clusters made from silver and other metals. Surprisingly enough, these so-called super atoms (clusters of 13 silver atoms, for example) ...

Brian Resnick was Vox’s science and health editor and is the co-creator of Unexplainable, Vox’s podcast about unanswered questions in science. The International Union of Pure and Applied Chemistry ...

The periodic table of the elements, principally created by the Russian chemist, Dmitry Mendeleev (1834-1907), celebrated its 150th anniversary last year. It would be hard to overstate its importance ...

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 ...

Massive explosion? Global annihilation? The sound of silence? What would happen if every element were combined, all at once? There are two ways to go about testing this, neither of which are practical ...
