Chapter 11, Problem 11F.12P

(a)

Interpretation Introduction

Interpretation:

The atom multiplicity which is permitted for the ground state of ${\text{O}}_{\text{2}}$ molecule when it dissociate into atoms has to be stated.

Concept introduction:

The quantum number $s$ is used to represents the total spin angular momentum of a particle.  The value of $s$ is a characteristic value of a particle. The value of $s$ for electron is $\frac{1}{2}$ and electrons will have a same value of $s$.  The symbol $S$ represents the vector sum of spin angular momentum.  The multiplicity is given by the formula as shown below.

  $\text{Multiplicity}=2S+1$

(b)

Interpretation Introduction

Interpretation:

The atom multiplicity which is permitted for the ground state of ${\text{N}}_2$ molecule when it dissociates into atoms has to be stated.

Concept introduction:

As mentioned in the concept introduction in part (a).
