  1. Warm Up 21: First determine if ionic or covalent, then give the name or formula 1. CaSO4 2. VO2 3. N2O7 4. Tin (IV) selenide 5. diseleniumdiiodide 6. Ammonium oxide

  2. Warm Up 4.3: Determine name or formula • CaSO4 Ionic: Ca is a metal calcium sulfate 2. VO2 Ionic: Vanadium is a metal Vanadium(IV) oxide 3. N2O7 Covalent: Nitrogen is nonmetal Dinitrogenheptoxide

  3. 4. Tin (IV) selenide Ionic: tin is a metal Sn2Se4 reduce = SnSe2 +4 -2

  4. 5. diseleniumdiiodide Covalent: there are prefixes Se2I2 6. Ammonium oxide Ionic: Ammonium is a polyatomic (NH4)2 O +1 -2
