Write the number of each atom in the chemical formulas for all of the possible combinations of positive and negative ions found on the cards. You can use the cards to figure out the formula by making as many copies of the cards as necessary to get them to line up exactly equally.

Example:

NaCl_

The chemical formula is NaCl, so you would place a 1 in the box for both Na and Cl.
