Chapter 12, Problem 22E

Interpretation Introduction

(a)

Interpretation:

The noble gas with which the cation ${\text{Sc}}^{\text{3+}}$ is isoelectronic is to be stated.

Concept introduction:

Isoelectronic means the total number of electrons of one element is equal to another element. Isoelectronic species can also be expressed in terms of electronic configuration by equating their general electronic configuration of the outermost shell.

Interpretation Introduction

(b)

Interpretation:

The noble gas with which the cation ${\text{K}}^{\text{+}}$ is isoelectronic is to be stated.

Concept introduction:

Isoelectronic means the total number of electrons of one element is equal to another element. Isoelectronic species can also be expressed in terms of electronic configuration by equating there general electronic configuration of the outermost shell.

Interpretation Introduction

(c)

Interpretation:

The noble gas with which the cation ${\text{Ti}}^{\text{4+}}$ is isoelectronic is to be stated.

Concept introduction:

Isoelectronic means the total number of electrons of one element is equal to another element. Isoelectronic species can also be expressed in terms of electronic configuration by equating there general electronic configuration of the outermost shell.

Interpretation Introduction

(d)

Interpretation:

The noble gas with which the cation ${\text{Ba}}^{\text{2+}}$ is isoelectronic is to be stated.

Concept introduction:

Isoelectronic means the total number of electrons of one element is equal to another element. Isoelectronic species can also be expressed in terms of electronic configuration by equating there general electronic configuration of the outermost shell.
