Use arrow keys to navigate and browse across all 118 elements. The selected element appears in gold on the Periodic Table on the left, and 22 data points for that element will display on the right.

Electron shells of the first ordinary elements of the periodic table. In chemistry and atomic physics, an electron shell may be thought of as an orbit followed by electrons around an atomic nucleus.

Oganesson, named for Russian physicist Yuri Oganessian (SN: 1/21/17, p. 16), is the heaviest element currently on the periodic table, weighing in with a huge atomic mass of about 300.
