Chapter 23, Problem 23.33P

(a)

Interpretation Introduction

Interpretation:

The electronic configuration of $C{e}^{2+}C{e}^{3+}andC{e}^{4+}$ has to be written.

Concept introduction:

Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.

(b)

Interpretation Introduction

Interpretation:

The electronic configuration of $Y{b}^{2+}Y{b}^{3+}andY{b}^{4+}$ has to be written.

Concept introduction:

Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.

(c)

Interpretation Introduction

Interpretation:

The stability of $C{e}^{4+}andY{b}^{2+}$ has to be explained.

Concept introduction:

Oxidation number: (Oxidation state) A number equal to the magnitude of the charge an atom would have if its shared electrons were transferred to the atom that attracts them more strongly.
