  1. Naming Ionic Compounds Unit 5

  2. The Rules for Naming Chemical Compounds Set by the IUPAC International Union of Pure and Applied Chemists

  3. Type I Ionic Compounds • Only 1 kind of charge • The cation is called by its element name • Example – calcium, potassium, radium

  4. Positive Ions • Monatomic cations (a single atom with a positive charge) take the name of the element plus the word "ion”

  5. Negative Ions • Monatomic (one atom) anions • Change their ending to "-ide”

  6. Anion Names • Carbon becomes Carbide • Oxygen become Oxide • Nitrogen - • Fluorine - • Sulfur - • Chlorine -

  7. ALWAYS Use This Order • Cation name first • Then the anion name

  8. Put the 2 ions together • MgCl2 Magnesium chloride • NOTE: The ONLY way to know the NUMBER of each atom is to use the oxidation # to figure out the ratio • The name does NOT tell you the ratio • Li2O Lithium Oxide

  9. Try to name these ionic compounds • NaF • CsCl • BaO • BeBr2 • K3N • ZnSe

  10. Write the Formulas • Lithium iodide • Sodium oxide • Potassium selenide • Magnesium fluoride • Cesium phosphide

  11. Polyatomic Ions • Shown in Reference Table • Charge applies to entire ion

  12. Examples • NaOH Sodium hydroxide • The polyatomic ions combine, and are named, as a unit • Mg(OH)2 Magnesium hydroxide • NOTE: This compound combines in a 1:2 ratio • When the ratio with a polyatomic ion is not 1:1, use parentheses

  13. Write the name CaSO4 AgNO3 Ba(C2H3O2)2 MgCr2O7

  14. Write the Formula • Ammonium hydroxide • Magnesium carbonate • Calcium sulfate • Calcium hydroxide • Zinc sulfide

  15. Type II Ions • More than one possible charge • Charge written as a Roman numeral in parentheses • Example: • Fe (II) ion Fe2+ • Or Fe (III) ion Fe3+
