1 Polyatomic Ions What is a cation afraid of? Answer: A dogion…

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, NH4+. There are many polyatomic anions. Except for the hydroxide ion, the names of the

3 Common polyatomic ions.
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.
