Question

When naming a binary compound, what ending do you use to represent anions?

Answer 1

You use the suffix "-ide". The cations are named 'as is'.

Explanation:

The anions are the negative ions, that gather at the positive electrode in electrolysis.

Some examples:
`Cl^(-) =`chloride, as in `NaCl=`sodium chloride
`S^(2-) =`sulfide, as in `FeS=`iron(II) sulfide
