Chapter 12, Problem 28A

(a)

Interpretation Introduction

Interpretation:

The species having small size is to be indicated.

Concept introduction:

Cations are always smaller than their parent atoms and anions are always larger than their parent atoms.

In periodic table, from left to right in a period size decreases and from top to bottom, size increases.

Answer to Problem 28A

  Mg2+

Explanation of Solution

  Mg2+ is smaller than Mg because cations are always smaller than their parent atoms.

(b)

Interpretation Introduction

Interpretation:

The species having small size is to be indicated.

Concept introduction:

Cations are always smaller than their parent atoms and anions are always larger than their parent atoms.

In periodic table, from left to right in a period size decreases and from top to bottom, size increases.

Answer to Problem 28A

  Ca2+

Explanation of Solution

  Ca2+ is smaller than K+ because in isoelectronic species, more the nuclear charge, smaller is the size.

Since, nuclear charge or number of protons/atomic number is more in Ca thus, it will be smaller in size.

(c)

Interpretation Introduction

Interpretation:

The species having small size is to be indicated.

Concept introduction:

Cations are always smaller than their parent atoms and anions are always larger than their parent atoms.

In periodic table, from left to right in a period size decreases and from top to bottom, size increases.

(c)

Answer to Problem 28A

  Br

Explanation of Solution

  Br is smaller than Rb+ because bromine belongs to halogens and rubidium is alkali metal.

And alkali metals are largest in periodic table.

(d)

Interpretation Introduction

Answer to Problem 28A

  Se

Explanation of Solution

  Se is smaller than Se2 because anions are always larger than their parent atoms.
