Chapter 23, Problem 23.83P

(a)

Interpretation Introduction

Interpretation:

The number of $d$ electron present in the central metal ion of ${\text{[Ru(NH}}_{\text{3}}{\text{)}}_{\text{5}}{\text{Cl]SO}}_{\text{4}}$ has to be identified.

Concept introduction:

The number of $d$ electrons in a central metal ion, first write the electron configuration for the metal atom.  The correct number of electrons, beginning with the $ns$ electrons and then the $\left(n–1\right)d$ electrons.

(b)

Interpretation Introduction

Interpretation:

The number of $d$ electron present in the central metal ion of ${\text{Na}}_{\text{2}}{\text{[Os(CN)}}_{\text{6}}\text{]}$ has to be identified.

Concept introduction:

The number of $d$ electrons in a central metal ion, first write the electron configuration for the metal atom.  The correct number of electrons, beginning with the $ns$ electrons and then the $\left(n–1\right)d$ electrons.

(c)

Interpretation Introduction

Interpretation:

The number of $d$ electron present in the central metal ion of ${\text{[Co(NH}}_{\text{3}}{\text{)}}_{\text{4}}{\text{CO}}_{\text{3}}\text{I]}$ has to be identified.

Concept introduction:

The number of $d$ electrons in a central metal ion, first write the electron configuration for the metal atom.  The correct number of electrons, beginning with the $ns$ electrons and then the $\left(n–1\right)d$ electrons.
