Chapter 23, Problem 23.81P

(a)

Interpretation Introduction

Interpretation:

The number of d electrons present in the central metal of $C{r}^{2+}ion$ has to be identified.

Concept introduction:

The charge on the central metal ion, and then the ion’s configuration by removing the correct number of electrons, beginning with the $ns$ electrons and then the $\left(\text{n– 1}\right)\text{d}$ electrons.

(b)

Interpretation Introduction

Interpretation:

The number of d electrons present in the central metal of $M{n}^{4+}ion$ has to be identified.

Concept introduction:

The charge on the central metal ion, and then the ion’s configuration by removing the correct number of electrons, beginning with the $ns$ electrons and then the $\left(\text{n– 1}\right)\text{d}$ electrons.

(c)

Interpretation Introduction

Interpretation:

The number of d electrons present in the central metal of $R{h}^{3+}ion$ has to be identified.
