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. 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! I've got a huge collection of printable periodic tables, which include all 118 elements. If you don't find what you need, just let me know and I'll have it made for you!
