  1. Ionic Compounds: Naming

  2. Naming Binary Ionic Compounds • Always name metal (the cation/+ ion) first 2. Write stem of nonmetal (the anion/ - ion) 3. Add ending “ide” to nonmetal Binary = only 2 types of elements (two capital letters)

  3. Nitr Ox Fluor Phosph Sulf Chlor Arsen Selen Brom Tellur Iod Hydr is the stem for H Stems of nonmetals

  4. Metals with one oxidation state • CaO • BaS • AlN • LiCl • Al2Se3 • Na2O • K3N • MgF2 Calcium Oxide Barium Sulfide Aluminum Nitride Lithium Chloride Aluminum Selenide Sodium Oxide Potassium Nitride Magnesium Fluoride

  5. The First Step in Naming • Find metal on PT • If metal has only one oxidation state it’s easy • If metal has more than one oxidation state, there’s an extra step

  6. Metals with > 1 oxidation state • Use formula to figure out which oxidation state metal ion has • Ex: Fe can be Fe+2or Fe+3 • Name FeO and Fe2O3

  7. FeO Name: Iron (II) oxide (roman numeral II = charge on Fe)

  8. Fe2O3 Name: Iron (III) oxide (roman numeral III = charge on Fe)

  9. Name the following Titanium (III) chloride • TiCl3 • MnO2 • AuCl3 • MnO Manganese (IV) oxide Gold (III) chloride Molybdenum (III) nitride

  10. Naming compounds with polyatomics • If it contains a polyatomic, same rule, just write the name polyatomic ion (Table E)

  11. Name the following Sodium hydroxide • NaOH • LiNO3 • Al(NO3)3 • Fe(OH)2 Lithium nitrate Aluminum nitrate Iron (II) hydroxide
