Study Notes
Ionic Compounds Overview
- Ionic compounds are formed by the transfer of electrons between metals and nonmetals, creating charged ions.
- The names and formulas of ionic compounds typically consist of the cation (positive ion) followed by the anion (negative ion).
Common Ionic Compounds and Their Formulas
- Lithium Sulfide: Li2S combines lithium and sulfur.
- Calcium Oxide: CaO consists of calcium and oxygen.
- Magnesium Nitride: Mg3N2 is formed by magnesium and nitrogen.
- Zinc Bromide: Represented as ZnBr2, formed from zinc and bromine.
- Magnesium Chloride: Denoted as MgCl2, consisting of magnesium and chlorine.
- Thorium Sulfide: Written as ThS2, made from thorium and sulfur.
Transition Metal Compounds and Their Nomenclature
- Copper (II) Bromide: Named for Copper with a +2 oxidation state as CuBr2.
- Lead (II) Oxide: Formed of lead with a +2 oxidation state, represented as PbO.
- Mercury (II) Phosphide: Written as Hg3P2 for Mercury in a +2 oxidation state.
Formulas of Specific Ionic Compounds
- Mercury (I) Oxide: The formula is Hg3O, indicating a +1 oxidation state for mercury.
- Gold (III) Chloride: Represented as AuCl3, showing gold in a +3 oxidation state.
