Chapter 5, Problem 5.106AQAP

Interpretation Introduction

(a)

Interpretation:

The more metallic element in the pair Sn or As should be identified.

Concept Introduction:

According to periodic trends, the atomic size of the element increases from top to bottom, thus, the amount of energy required removing an electron from its outermost shell decreases and it can easily give an electron and show metallic characteristic. Thus, on moving top to bottom, metallic character of an element increases.

Similarly, on moving left to right in a period, atomic size decreases thus, amount of energy required to remove an electron increases and it is difficult to remove an electron. Thus, non-metallic character increases.

Interpretation Introduction

(b)

Interpretation:

The more metallic element in the pair Cl or I should be identified.

Concept Introduction:

According to periodic trends, the atomic size of the element increases from top to bottom, thus, the amount of energy required removing an electron from its outermost shell decreases and it can easily give an electron and show metallic characteristic. Thus, on moving top to bottom, metallic character of an element increases.

Similarly, on moving left to right in a period, atomic size decreases thus, amount of energy required to remove an electron increases and it is difficult to remove an electron. Thus, non-metallic character increases.

Interpretation Introduction

(c)

Interpretation:

The more metallic element in the pair Ca or Ba should be identified.

Concept Introduction:

According to periodic trends, the atomic size of the element increases from top to bottom, thus, the amount of energy required removing an electron from its outermost shell decreases and it can easily give an electron and show metallic characteristic. Thus, on moving top to bottom, metallic character of an element increases.

Similarly, on moving left to right in a period, atomic size decreases thus, amount of energy required to remove an electron increases and it is difficult to remove an electron. Thus, non-metallic character increases.

Interpretation Introduction

(d)

Interpretation:

The more metallic element in the pair Ba or Hg should be identified.
