  1. Ionic Compound
    For Nomenclature purposes an ionic compound is a compound resulting from the combination of a metal and one or more non-metals.
  2. Molecular Compound
    For Nomenclature purposes a molecular compound is a compound resulting from the combination of a non-metal with other non-metals.
  3. Compounds with Positively Charged Polyatomic Ions
    for nomenclature purposes and compound containing a positively charged polyatomic ion (a combination of non-metals) is considered to be functioning as a metal, making it ionic,
  4. Nomenclature for Binary Ionic Compounds: Fixed Charge Metals
    The full name of the element plus the word "ion"

    Example: Sodium Ion
  5. Nomenclature for Binary Ionic Compounds: Variable Charge Metals
    The full name of the element followed by a Roman numeral in parentheses that gives the charge, followed by the word "ion"

    Example: Iron (II) Ion
  6. Nomenclature for Binary Ionic Compounds: Non-Metal Ions
    Take the stem of the name of the element, followed by the suffix "-ide", followed by the word "ion"

    Example: O2- is oxide ion
  7. Nomenclature for Fixed Charge Binary Ionic Compounds
    The full name of the metallic element first, followed by the stem of the nonmetallic element combine with the suffix "-ide"

    Example: NaF is Sodium Fluoride
  8. Nomenclature for Variable Charge Binary Ionic Compounds
    The full name of the metallic element first, followed by a Roman numeral in parentheses denoting the charge of the metal, followed by the stem of the nonmetallic element combine with the suffix "-ide"

    Example: FeCl2 is Iron (II) Chloride while FeCl3 is Iron (III) Chloride
  9. Nomenclature for Ionic Compounds containing Polyatomic Ions
    The basis of the rule is this: the full name of the metallic element first, followed by the stem of the nonmetallic element combine with the suffix "-ide"

    • You will substitute into the above rule the name of the polyatomic ion based on the following rule:
    • 1. If the Polyatomic ion is positive it replaces the name of the metal.
    • 2. If the Polyatomic ion is negative it replaces the name of the non-metal (it also does no use the "-ide" suffix)
    • 3. If there are two polyatomic ions, one positive and one negative, dual substitution occurs
  10. Naming Binary Molecular Compounds
    Named in order in which they appear in the formula.

    The full name of the element first, followed by the stem of the second element combined with the suffix "-ide"

    Numerical prefixes are used to precede each element, giving the number of atoms present.

    Example: N2O5 is dinitrogen pentoxide
  11. Naming Acids: -ide Rule
    When the name of the negative ion produced from the acid ends in "ide"

    • 1. the Prefix Hydro-
    • 2. the stem of the name of the negative ion
    • 3. the suffix -ic
    • 4. the word acid

    Example: HCl is Hydrochloric acid
  12. Naming Acids: -ate Rule
    When the name of the negative ion produced from the acid ends in "ate"

    • 1. the name of the negative ion, minus the "-ate" suffix
    • 2. the suffix -ic
    • 3. the word acid

    Example: HNO3 is Nitric acid
  13. Naming Acids: -ite Rule
    When the name of the negative ion produced from the acid ends in "ite"

    • 1. the name of the negative ion, minus the "-ite" suffix
    • 2. the suffix -ous
    • 3. the word acid

    Example: HNO2 is Nitrous acid
  14. Naming a series of Oxyacids
    Number of Oxygen Atoms = N

    • N + 1 = per______ic Acid
    • N       = _________ic Acid
    • N - 1  = _________ous Acid
    • N - 2 (or more) = Hypo______ous Acid
