Question

Calculate the oxidation number of atoms

Answer 1

Explanation:

1.The oxidation number of a free element is always 0.

2.The oxidation number of a monatomic ion equals the charge of the ion.

3.The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements.

4.The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.

Answer 2

Answer:

The oxidation number of a free element is always 0.

The oxidation number of a monatomic ion equals the charge of the ion.

The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements.

The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
