The periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic ...

The periodic table is one of the triumphs of science. Even before certain elements had been discovered, this chart could successfully predict their masses, densities, how they would link up with other ...

Since the turn of the century, six new chemical elements have been discovered and subsequently added to the periodic table of elements, the very icon of chemistry. These new elements have high atomic ...

Carolyn Krause presents the second part of the three-part series on the Oak Ridge National Laboratory's role in the discovery of elements in the periodic table. Many of them have been synthesized ...

For new, human-made heavy elements on the periodic table, being “too ‘big’ for your own good” often means instability and a fleeting existence. The more protons and neutrons scientists squeeze ...
