The most-requested printable periodic table has been one for 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. 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, particularly metals, may carry other charges.
