Table of Valences of the Elements

A lithium atom has one outer shell electron, so it's usual valence is +1, but it can lose the electron and have a valence of -1.

A lithium atom has one outer shell electron, so it’s usual valence is +1, but it can lose the electron and have a valence of -1.

This is a table of the valences or oxidation states of the elements. The most common valences are in BOLD. Values in italics are predicted theoretical values.

This information is available on a Color Periodic Table of the Elements or a Black and White version. A simpler version listing only the most common valence charges is also available.
