Answered by Ezhilvendhan001

5

The sum of the oxidation numbers in a neutral compound is zero. 10. The sum of the oxidation numbers in a polyatomic ion is equal to the charge on the ion. The oxidation number of the sulfur atom in the SO42- ion must be +6, for example, because the sum of the oxidation numbers of the atoms in this ion must equal -2.
