  1. Naming Compounds

  2. Binary Ionic Compounds Binary compounds contain only two elements (prefix bi means two…like bicycle) Remember an ionic compound is between a metal and nonmetal. When naming, simply state the name of the metal first, then the nonmetal, changing the ending to –ide NaCl = sodium chloride

  3. Molecular (covalent) compounds Name the first element, then change the ending of the second element to –ide NBr = nitrogen bromide

  4. Molecular compounds with multiple atoms You must use prefixes to show the number of atoms in each element

  5. Examples NO2 nitrogen dioxide (the prefix mono is not used on the first element in the compound) N2O4dinitrogentetraoxide

  6. Polyatomic Ions NH4+ Ammonium OH- Hydroxide NO3- Nitrate SO42- Sulfate
