It is equal to the charge. Oxidation number is equal to -2.
-2 for S in sulphides
There are two s atoms. One shows 0 and other shows+6.
The oxidation number of monoatomic ions is the same as their ion charge: +2 in Fe(II) for Fe2+, +3 in Fe(III) for Fe3+, -2 in sulfide S2-
The oxidation number is a measure of the charge an atom would have if all its bonds were 100% ionic. It can be positive, negative or zero.
The charge. Cations and anions have an oxidation number equal to their charge, for example in Fe2+, Fe hasan oxidation number of +2 and in S2- S has an oxidation number of -2. Uncharged atoms have zero oxidation number.
oxidation number of I is -1. oxidation number of F is +1.
