This is a chart of the most common charges for atoms of the chemical elements. You can use this chart to predict whether or not an atom can bond with another atom. The charge on an atom is related to its valence electrons or oxidation state. An atom of an element is most stable when its outer electron shell is completely filled or half-filled. The most common charges are based on maximum stability for the atom.

However, other charges are possible.

For example, hydrogen sometimes has a charge of 0 or (less commonly) -1. Although noble gas atoms almost always carry a charge of 0, these elements do form compounds, which means they can gain or lose electrons and carry a charge.
