1. Polyatomic Ions

2. Many ionic compounds are not binary because one or both ions contain atoms of more than one element. These polyatomic ions consist of two or more different non-metal atoms, which are joined by covalent bonds. There is only one common polyatomic cation: the ammonium ion, NH 4 +. There are many polyatomic anions. Except for the hydroxide ion, the names of the

3. anions end in “-ate” instead of “ide”. Writing formulas is also the same, except that you have to add parentheses when the formula requires more than one polyatomic ion. Common polyatomic ions.
