Thus, for example, for the Ca2+and O2– ions in calcium oxide, we get Ca 2 O 2, which we reduce to the formula CaO.* The following two sample problems apply these rules.8, we name the compound from its elements, and in Sample Problem 2.

You need three positively charged copper ions to balance out the –3 charge of the nitride ion, so the formula is Cu 3 N.Lead(II) is the Pb 2+ ion, and oxide, O 2–, is the ionic form of the oxygen atom.The +2 charge of the Pb cancels out the –2 charge of the O, so the formula is PbO.
