5. Naming Compounds Chapter 6

6. Tips for Naming Table Between what types of elements? Electron movement? Naming tips? IonicCovalent Metal and NonmetalNonmetal and Nonmetal Electrons are transferred Creates ions (+/-) Electrons are shared 1. Add –ide to the end of the nonmetal 2. Transition metals  identify charge (Roman Numerals) 1.Use prefixes (mono,di, etc) 2.Add –ide to end 3.No prefix on first atom if it only contains 1 atom
