5. Writing formulas from the names Follow the following steps. 1. Write the most probable ions for each elements name. potassium oxide K+1 O-2 2. Use the criss-cross method or find the least common multiple of the two charges. K+1 O-2 K2 O 3. If you use the criss-cross method, remember to reduce the subscripts if needed. Mg2O2 ? MgO
