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 ...

The periodic table may soon gain a new element, physicists at Lund University in Sweden announced Tuesday. A team of Lund researchers is the second to successfully create atoms of element 115.

At the far end of the periodic table is a realm where nothing is quite as it should be. The elements here, starting at atomic number 104 (rutherfordium), have never been found in nature. In fact, they ...

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 ...
