(a)

Interpretation Introduction

Interpretation: The oxidation number of nitrogen in the given elements is to be assigned.

Concept introduction: Oxidation number is defined as the charge present on ions. When an atom forms a chemical bond with another atom, the number of electrons that an atom gain or loses is the oxidation number. It is also known as oxidation state.

To determine: The oxidation number of nitrogen in ${\text{NO}}_{\text{2}}$.

(b)

Interpretation Introduction

To determine: The oxidation number of nitrogen in ${\text{N}}_{\text{2}}\text{O}$.

(c)

Interpretation Introduction

To determine: The oxidation number of nitrogen in ${\text{HNO}}_{\text{3}}$.
