The periodic table has become an icon of science. Its rows and columns provide a tidy way of showcasing the elements — the ingredients that make up the universe. It seems obvious today, but it wasn’t ...

A century and a half ago, a Russian chemistry professor published a classification of all the known elements, organized by atomic weight. Today, the system that he created for his students — plus some ...

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory are using the 88-Inch Cyclotron to help steady the famous periodic table of elements one atom at a time where it's gone a ...

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 ...

On the periodic table, most elements have at least one stable form. But others have only unstable forms, all of which decay by emitting radiation and transforming into different elements until ...

Since the invention of the periodic table 150 years ago this month, scientists have worked to fill in the rows of elements and make sense of their properties. But researchers have also pursued a ...

Countless periodic table posters are now obsolete. Meet the newest elements: nihonium (Nh), moscovium (Mc), tennessine (Ts) and oganesson (Og). On November 28, the International Union of Pure and ...

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 ...

Four new chemical elements now have official names and symbols, the International Union of Pure and Applied Chemistry (IUPAC) announced this week. After a five-month review, IUPAC chemists have ...
