Chapter 20, Problem 5RQ

Interpretation Introduction

Interpretation: The valence electron configuration for the group $4\text{A}$ elements is to be stated. The two most important elements on the earth that is found in group $4\text{A}$ elements and reason of their importance is to be stated. The change observed in metallic character of group $4\text{A}$ elements as one goes down the group is to be stated. The three allotropic forms of carbon is to be stated. Important properties of germanium, tin and lead is to be stated. The formulas of the compounds formed when $\text{Ge}$ reacts with the given elements are to be predicted.

Concept introduction: Group $4\text{A}$ elements are highly reactive. They form covalent bonds when react with non-metals.

To determine: The valence electron configuration for group $4\text{A}$ elements; the two most important elements on the earth that is found in group $4\text{A}$ elements and reason of their importance; the change observed in metallic character of group $4\text{A}$ elements as one goes down the group; the three allotropic forms of carbon; the important properties of germanium, tin and lead; the formulas of the compounds formed when $\text{Ge}$ reacts with ${\text{F}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$.
