Periodic Table With Common Ionic Charges

The most-requested printable periodic table lists element charges, to predict compounds and chemical reactions. Now, you can use periodic table trends to predict the most common element charges. Group I (alkali metals) carry a +1 charge, Group II (alkaline earths) carry a +2, Group VII (halogens) carry -1, and Group VIII (noble gases) carry a 0 charge. Metal ions may have other charges or oxidation states. For example, copper usually has a +1 or +2 valence, while iron typically has a +2 or +3 oxidation state. The rare earths often carry many different ionic charges.

Color Periodic Table of the Elements With Charges

By Anne Marie Helmenstine, Ph.D.

One of the reasons you don't normally see a table with charges is because the organization of the table offers a clue to common charges, plus elements can have just about any charge given enough energy and the right conditions. Even so, here's a table of element charges for readers seeking the most common ionic charges of element atoms. Just keep in mind elements may carry other charges. For example, hydrogen can carry -1 in addition to +1. The octet rule doesn't always apply to ionic charges. In some cases, the charge can exceed +8 or -8!
