Naming Ionic Compounds with Two
Elements
To name a compound that contains two elements,
• identify the cation
and anion. • name the cation
first, followed by the name of the anion with an –ide ending.

Study Tip: Ionic or Covalent
A compound is
• ionic if the first element in the formula
or the name is a metal or the polyatomic ion NH4+ .
K2O K is a metal; compound is ionic;
potassium oxide
• covalent if the first element in the formula or the name
is a nonmetal.
N2O N is a nonmetal; compound is covalent;
dinitrogen oxide
