Chapter 8, Problem 8.79P

(a)

Interpretation Introduction

Interpretation:

The number of unpaired electrons present in the ground state atom from the $2\text{A}\left(2\right)$ group is to be determined.

Concept introduction:

The ground state electronic configuration is the arrangement of electrons around the nucleus of an atom with the lower energy levels. When an electron absorbs some amount of energy, it jumps to the higher orbital. It again comes back to the lower state with the release of energy.

(b)

Interpretation Introduction

Interpretation:

The number of unpaired electrons present in the ground state atom from the $\text{5A}\left(15\right)$ group is to be determined.

Concept introduction:

The ground state electronic configuration is the arrangement of electrons around the nucleus of an atom with the lower energy levels. When an electron absorbs some amount of energy, it jumps to the higher orbital. It again comes back to the lower state with the release of energy.

(c)

Interpretation Introduction

Interpretation:

The number of unpaired electrons present in the ground state atom from the $8\text{A}\left(18\right)$ group is to be determined.

Concept introduction:

The ground state electronic configuration is the arrangement of electrons around the nucleus of an atom with the lower energy levels. When an electron absorbs some amount of energy, it jumps to the higher orbital. It again comes back to the lower state with the release of energy.

(d)

Interpretation Introduction

Interpretation:

The number of unpaired electrons present in the ground state atom from the $\text{3A}\left(13\right)$ group is to be determined.

Concept introduction:

The ground state electronic configuration is the arrangement of electrons around the nucleus of an atom with the lower energy levels. When an electron absorbs some amount of energy, it jumps to the higher orbital. It again comes back to the lower state with the release of energy.
