nomenclature of ionic compounds

How does the periodic table help in predicting the formula of a stable ionic compound? Metals in Group 1 form cations with a -1 charge. Metals in Group 2 form cations with a +2 charge. Metals in Group 1 form anions with a +1 charge. Metals in Group 2 form anions with a -2 charge.
