  1. Honors Chemistry Podcast 4.2 Chemical Nomenclature and Formula Writing

  2. Ionic Compounds • Formed from metals losing electrons to nonmetals resulting in ions of opposite charges. Na Cl

  3. Formation of Ions

  4. Formation of Ions

  5. Nomenclature (naming) • Metal ion always goes first • Nonmetal ion changes name ending to –ide NaBr CaCl2

  6. Name the following ionic compounds • Li2S • K3P • CaO • Sr3N2 • MgI2

  7. Formula Writing • Metal (positive ion) first • Balance charge of ions to form a neutral compound • Examples: • Magnesium nitride Sodium Sulfide
