  1. Nomenclature and Mixtures Naming Compounds, Identifying Mixtures, Separation Techniques

  2. Nomenclature • Naming Chemical Compounds • Three Types:

  3. Nomenclature • Type A: Ionic • Metals with known charge + Nonmetals

  4. Nomenclature • Type B: Ionic • Metals with UNKNOWN charge + Nonmetals

  5. Nomenclature • Type C: COVALENT • Nonmetal + Nonmetal

  6. Let’s Practice, Shall We?? • Name the following using Type A rules: • LiCl • MgI2 • Na2O • Now go the other way: • Beryllium Nitride • Calcium Selenide • Hydrogen Chloride (a.k.a. hydrochloric acid)

  7. Let’s Practice, Shall We?? • Name the following using Type B rules: • Fe2O3 • FeO • CrCl2 • Now go the other way: • Manganese (I) Bromide • Nickel (II) Phosphide • Cobalt (III) Selenide

  8. Let’s Practice, Shall We?? • Name the following using Type C rules: • CO2 • CO • N2O3 • CCl4 • And, yes let’s go backwards one last time • Sulfur Dioxide • TrinitrogenHexaoxide • Oxygen Dichloride

  9. Nomenclature • Practice: • Chromium (III) Chloride • Li2O • Rubidium Oxide • Dihydrogen Monoxide • TrinitrogenHexaoxide • Iron (II) Fluoride

  10. Polyatomics • Sames rules apply • Just cancel out the charges • These use Type A and B rules, NOT Type C • NEVER USE A PREFIX WITH POLYATOMICS!! • Try: • Iron (III) Hydroxide RbOH • Potassium Nitrate Li2SO4 • Hydrogen Sulfate HNO3 • Hydrogen Sulfide Na3PO4

  11. Nomenclature,IN A NUTSHELL • Type A: (works with polyatomics too) • Must know the charge • Cancel the charges out and name it • Add –ide to the end • Type B: (works with polyatomics too) • MUST use a Roman Numeral (tells us the charge) • Then name just like “A” • NEVER, EVER, EVER!!!! USE A PREFIX!!! EVERRR!! • Type C: (a polyatomic is metal so they CANNOT be used here  two nonmetals only!! • MUST use a PREFIX, ONLY with two nonmetals!!
