For years, physicists have mapped the stability of atomic nuclei with remarkable confidence. The periodic table, with its ...

At first glance, the system of chemical elements published by Dmitri Mendeleev in 1869 bears little resemblance to the modern periodic table. But by listing elements in columns, and lining up the ...

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 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 ...

The periodic table may be one of the greatest accomplishments in information visualization. Its simple approach–lining and layering atoms by number of protons–is something that anyone can understand.

The story of the fifteenth element began in Hamburg, in 1669. The unsuccessful glassblower and alchemist Hennig Brandt was trying to find the philosopher’s stone, a mythical substance that could turn ...

Posters in chemistry labs are in need of an update. The periodic table now has four new elements, completing its seventh row. The International Union of Pure and Applied Chemistry (IUPAC) and the ...
