Chapter 6, Problem 6.37P

(a)

Interpretation Introduction

Interpretation:

The pair $\left({\text{Li,Li}}^{\text{+}}\right)$ that has relative larger size has to be given.

Concept Introduction:

Rules to compare the size of two ions:

• For ions from the same parent species, cation is smaller in ion than its parent and anion is bigger.

  For example: ${\text{Na}}^{\text{+}}$ ion is smaller than sodium, chlorine ion is bigger than chlorine.

• Higher the magnitude of charge on cation smaller is the size of the cation.

  For example:  ${\text{Fe}}^{\text{2+}}$ is bigger than ${\text{Fe}}^{\text{3+}}.$

• Higher than magnitude of charge on anion larger the size of anion.

  For example:  ${\text{N}}^{\text{2-}}$ is smaller than ${\text{N}}^{\text{3-}}\text{.}$

(b)

Interpretation Introduction

(d)

Interpretation Introduction

Interpretation:

The pair $\left({\text{O}}^{\text{2-}}{\text{,O}}^{\text{2+}}\right)$ that has relative larger size has to be given.
