  • Naming Ionic Compounds with Polyatomic Ions
  • Slide 52
  • Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions.
  • Slide 53
  • You can tell how many elements a compound has by counting the number of capital letters in the formula.
  • Slide 54
  • Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions. You can tell how many elements a compound has by counting the number of capital letters in the formula. For example: CuSO 4 has 3 capital letters, so it has 3 elements.
  • Slide 55
  • Any ionic compound with more than 2 elements can be assumed to contain one or more polyatomic ions. You can tell how many elements a compound has by counting the number of capital letters in the formula. For example: CuSO 4 has 3 capital letters, so it has 3 elements. Because CuSO 4 has more than 2 elements, It must contain a polyatomic ion.
  • Slide 56
  • Once we know that a compound contains one or more polyatomic ions, we just locate that ion, or those ions, on the ion table.
  • Slide 57
  • The name of a polyatomic ion is NOT CHANGED when it is added to the name of a compound.
  • Slide 58
  • For example:
  • Slide 59
  • NaClO is named sodium hypochlorite
  • Slide 60
  • For example: NaClO is named sodium hypochlorite KNO 3 is named potassium nitrate
  • Slide 61
  • For example: NaClO is named sodium hypochlorite KNO 3 is named potassium nitrate LiMnO 4 is named lithium permanganate
