Study Notes

Ionic Compounds Overview

  • Ions are charged atoms, which can be cations (positive) or anions (negative).
  • Cations: Formed when metals lose electrons; only metals can become cations.
  • Anions: Formed when nonmetals gain electrons; only nonmetals can become anions.
  • Ionic Bonds: Occur between metal and nonmetal atoms, where the metal loses electrons and the nonmetal gains them, resulting in a compound.

Key Ionic Compounds

  • LiBr: Lithium bromide
  • Cu₃N₂: Copper (II) nitride
  • MgCl₂: Magnesium chloride
  • PbS: Lead (II) sulfide
  • Al₂Se₃: Aluminum selenide

Chemical Formulas for Specific Compounds

  • K₃N: Potassium nitride
  • Al₂S₃: Aluminum sulfide
  • SnS₂: Tin (IV) sulfide
  • KOH: Potassium hydroxide
  • LiF: Lithium fluoride
  • K₂O: Potassium oxide
  • MgF₂: Magnesium fluoride
  • AlF₃: Aluminum fluoride
  • Ca₃N₂: Calcium nitride
  • Li₂S: Lithium sulfide
  • CaS: Calcium sulfide
  • KI: Potassium iodide
  • Na₂S: Sodium sulfide
  • Al₂S₃: Aluminum sulfide
  • AlN: Aluminum nitride
  • BaO: Barium oxide
  • CaBr₂: Calcium bromide
  • NaI: Sodium iodide
  • CaCl₂: Calcium chloride
  • K₂S: Potassium sulfide
  • LiNO₃: Lithium nitrate
  • Ca(NO₃)₂: Calcium nitrate
  • AlBr₃: Aluminum bromide
  • CaO: Calcium oxide
  • MgS: Magnesium sulfide
  • NaF: Sodium fluoride
  • BaF₂: Barium fluoride
  • Na₃N: Sodium nitride

Important Names and Formulas

  • Magnesium Chloride (MgCl₂): Commonly used in de-icing and as a supplement.
  • Calcium Nitrate (Ca(NO₃)₂): Often used in fertilizers.
  • Lithium Nitrate (LiNO₃): Functions in batteries and thermal storage systems.

Summary of Ionic Compound Naming Conventions

  • Cation named first, followed by anion.
  • Transition metals require Roman numerals to indicate charge.
  • Prefixes are not used; compounds are named based on oxidation states and charges.
