Chapter 22, Problem 22.1P

Interpretation Introduction

To determine:To find the non-metallic character of $\text{Ge}\text{}\text{or}\text{}\text{Br}$.

Concept introduction:

According to electron acceptance of the element electronegative character will be defined. When an anion is form then it is said to be non-metallic or electronegative in nature. For ex: chlorine, phosphorus, oxygen. These will show greater electronegativity or non-metallic characters than cations.

Answer to Problem 22.1P

Solution: Bromine has more non-metallic character in the pair $\text{Ge}\text{}\text{or}\text{}\text{Br}$

Explanation of Solution

Bromine and germanium both belongs to the same row in the periodic table. But bromine is placed on the right side of the table and germanium is placed on the left side of the table. Hence it is evident that bromine is more non-metallic than germanium.

c)

Interpretation Introduction

To determine:To find the non-metallic character of $\text{In}\text{}\text{or}\text{}\text{Se}$.

Concept introduction:

According to electron acceptance of the element electronegative character will be defined. When an anion is form then it is said to be non-metallic or electronegative in nature. For ex: chlorine, phosphorus, oxygen. These will show greater electronegativity or non-metallic characters than cations.

Answer to Problem 22.1P

Solution: Selenium has more non-metallic character in the pair $\text{In}\text{}\text{or}\text{}\text{Se}$

Explanation of Solution

Indium belongs to 3A and selenium belongs to 6A groups. The metallic character decreases as we go from left to right, thus, selenium is found to be more metallic as it is placed below the indium in the periodic table.

d)

Interpretation Introduction

To determine:To find the non-metallic character of $\text{Cl}\text{}\text{or}\text{}\text{Te}$.

Concept introduction:

According to electron acceptance of the element electronegative character will be defined. When an anion is form then it is said to be non-metallic or electronegative in nature. For ex: chlorine, phosphorus, oxygen. These will show greater electronegativity or non-metallic characters than cations.

Answer to Problem 22.1P

Solution: Chlorine has more non-metallic characters in the pair $\text{Cl}\text{}\text{or}\text{}\text{Te}$

Explanation of Solution

The chlorine has more non- metallic character than tellurium because chlorine lies above the tellurium in periodic table and also it is place right to tellurium.
