Chapter 12, Problem 26E

Interpretation Introduction

(a)

Interpretation:

Among $\text{Al}$ atom and $\text{Al}$ ion, the atom or ion having larger radius is to be stated.

Concept introduction:

Radius is the distance from the center of the nucleus to the outermost shell of the atom or ion. The radius of an atom is termed as its atomic radius. The radius of ion is termed as its ionic radius. The atomic and ionic radius both from top to bottom in a group.

Interpretation Introduction

(b)

Interpretation:

Among $\text{Pb}$ atom and $\text{Pb}$ ion, the atom or ion having the larger radius is to be stated.

Concept introduction:

Radius is the distance from the center of the nucleus to the outermost shell of the atom or ion. The radius of an atom is termed as its atomic radius. The radius of ion is termed as its ionic radius. The atomic and ionic radius both from top to bottom in a group.

Interpretation Introduction

(c)

Interpretation:

Among $\text{Se}$ atom or $\text{Se}$ ion, the atom or ion having the larger radius is to be stated.

Concept introduction:

Radius is the distance from the center of the nucleus to the outermost shell of the atom or ion. The radius of an atom is termed as its atomic radius. The radius of ion is termed as its ionic radius. The atomic and ionic radius both from top to bottom in a group.

Interpretation Introduction

(d)

Interpretation:

Among $\text{N}$ atom or $\text{N}$ ion, the atom or ion having the larger radius is to be stated.

Concept introduction:

Radius is the distance from the center of the nucleus to the outermost shell of the atom or ion. The radius of an atom is termed as its atomic radius. The radius of ion is termed as its ionic radius. The atomic and ionic radius both from top to bottom in a group.
