Chapter 8, Problem 8.49QE

(a)

Interpretation Introduction

Interpretation:

The order of the increasing size of the elements $\text{B}$, $\text{O}$ and $\text{Li}$ have to be determined.

Concept Introduction:

Atomic size is half of the distance between the adjacent atoms in the molecule. Since the electron cloud has no fixed boundary so the size of the atom is measured with high difficulty.

(b)

Interpretation Introduction

Interpretation:

The order of the increasing size of the elements $\text{C}$, $\text{N}$ and $\text{Si}$ have to be determined.

Concept Introduction:

Atomic size is half of the distance between the adjacent atoms in the molecule. Since the electron cloud has no fixed boundary so the size of the atom is measured with high difficulty.

(c)

Interpretation Introduction

Interpretation:

The order of the increasing size of the elements $\text{S}$, $\text{As}$ and $\text{Sn}$ have to be determined.
