  • Naming Monatomic Ions Monatomic cations are identified simply by the elements name. Examples: K + is called the potassium cation Mg 2+ is called the magnesium cation
  • Slide 7
  • Naming Monatomic Ions For monatomic anions, the ending of the elements name is dropped, and the ending ide is addend to the root name. Examples: F - is called the fluoride anion N 3+ is called the nitride anion
