Honors Chemistry Podcast 4.2

Chemical Nomenclature and

Formula Writing

ionic compounds
Ionic Compounds
  • Formed from metals losing electrons to nonmetals resulting in ions of opposite charges.

Na Cl

nomenclature naming
Nomenclature (naming)
  • Metal ion always goes first
  • Nonmetal ion changes name ending to –ide

NaBr

CaCl2

formula writing
Formula Writing
  • Metal (positive ion) first
  • Balance charge of ions to form a neutral compound
  • Examples:
  • Magnesium nitride Sodium Sulfide
