atoms vs ions1
Atoms vs. Ions
  • Atoms can gain or lose e- to form IONS
    • ANY charged particle is called an
    • Losing e- gives ______________________charge
      • Called ______________
      • Usually formed from metals
    • Gaining e- gives a _______________charged ion

Classification of Ions
  • Below is a flow chart for the classification of ions.
monoatomic cations
Monoatomic Cations
  • Metal atoms can lose valence electrons and become positively charged cations.
    • Na+ is named
    • Al3+ is named
metals that form multiple ions
Metals That Form Multiple Ions
  • If a metal can form more than one cation, it is named for the parent, followed by _____________________________, followed by the word “ion.”
    • Fe2+ is the
    • Fe3+ is the
monoatomic anions
Monoatomic Anions
  • Nonmetals can gain valence electrons and become negatively charged anions.
  • Monoatomic anions are named by dropping the end of the element name and adding ____________

summary of ionic nomenclature rules
Summary of Ionic Nomenclature Rules
  • Name to formula:
    • Write the symbol for each ion
    • Use the LCM of the charges to find the number of each ion needed
    • Write the formula
      • no charges should be written in the final formula
      • use parenthesis if and only if you need more than 1 polyatomic
  • Formula to name
    • Write the name of the cation first, then the name of the anion
      • if and only if cation is VOS, include roman numeral for charge
