Chapter 23, Problem 23.82P

(a)

Interpretation Introduction

Interpretation:

The number of $d$ electron present in the central metal ion of ${\text{Ca[IrF}}_{\text{6}}\text{]}$ 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.

(b)

Interpretation Introduction

Interpretation:

The number of $d$ electron present in the central metal ion of ${{\text{[HgI}}_{\text{4}}\text{]}}^{\text{2-}}$ 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 ${\text{[Co(EDTA)}}^{\text{2-}}\text{]}$ 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.
