In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure)...

This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise...

(period) is started when a new electron shell has its first electron. Columns (groups) are determined by the electron configuration of the atom; elements with...

dependent upon its electronic configuration. For a main-group element, a valence electron can exist only in the outermost electron shell; for a transition metal...

Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers...
