Oxyacids are named by changing the ending of the anion (-ate to –ic, and -ite to -ous) and adding “acid;” H 2 CO 3 is carbonic acid. These names consist of 2 parts. The name of least electronegative element is given first, with no ending. The base name of the most electronegative element is given last with an -ide ending , e.g., oxide, nitride, chloride. There are no other endings for covalent compounds.

The name of second element is shortened and the suffix "ide" is added.
