Chapter 20, Problem 6RQ

Interpretation Introduction

Interpretation: The valence electron configuration for the Group $5\text{A}$ elements is to be stated. The examples that illustrate the difference between metallic characteristics of $\text{Bi},\text{Sb}$ and $\text{N},\text{P,}\text{As}$ are to be stated. The reason for the fact, elemental nitrogen exists as ${\text{N}}_2$, whereas in the gas phase the elements phosphorus, arsenic, and antimony consist of ${\text{P}}_4$, ${\text{As}}_4$, and ${\text{Sb}}_4$ molecules is to be stated. The explanation of the fact, white phosphorus is much more reactive than black or red phosphorus.

Concept introduction: Group $5\text{A}$ elements are highly reactive. They form covalent bonds when react with non-metals.

To determine: The valence electron configuration for the Group $5\text{A}$ elements; the examples that illustrates the difference between metallic characteristics of $\text{Bi},\text{Sb}$ and $\text{N},\text{P,}\text{As}$; the reason for the fact ‘Elemental nitrogen exists as ${\text{N}}_2$, whereas in the gas phase the elements phosphorus, arsenic, and antimony consist of ${\text{P}}_4$, ${\text{As}}_4$, and ${\text{Sb}}_4$ molecules’; the explanation for the fact, white phosphorus is much more reactive than black or red phosphorus.
