Chapter 21, Problem 83PS

Interpretation Introduction

Interpretation: In the given species the $\text{Xe}$ with $+4$ oxidation state is to be stated.

Concept introduction:

Oxidation number is also called oxidation state. The total number of electrons that an atom gain or loss to form a chemical bond with another atom is known as its oxidation state.

Rules for assigning oxidation number

1. 1. The oxidation number of the atom of an uncombined element is zero.
2. 2. The sum of the oxidation numbers of all atoms in a compound must equal to the total charge on the species.
3. 3. Hydrogen has an oxidation number of +1 unless it is combined with metals, in which case it has an oxidation number of -1.
4. 4. Oxygen has an oxidation number of -2, except in peroxides where it is -1 and in $O{F}_2$ where it is +2.
