Periodic table with charges

This periodic table shows the charge of the ions each element most commonly forms. Metals lose electrons and form positive ions; nonmetals gain electrons and form negative ions.

The trend

Main-group charges follow the group: 1+ for the alkali metals, 2+ for the alkaline earth metals, 3+ for aluminium’s group, 3− for nitrogen and phosphorus, 2− for oxygen’s group and 1− for the halogens. Noble gases do not form ions. Transition metals often have more than one common charge, such as iron (2+ and 3+) and copper (1+ and 2+). Carbon and silicon usually share electrons instead of forming ions, so they are shown as 4±.
