Chapter 9, Problem 27E

Interpretation Introduction

Interpretation:

The reason of more reactivity of Group $1$ metals than that of group $2$ metals is to be explained.

Concept Introduction: Group $1$ metals i.e. alkali metals arehighly reactive as compared to the alkaline earth metals i.e. group $2$ metals. The reason behind this is the electronic configuration of the group $1$ is $n{s}^1$ and that for the group $2$ is $n{s}^2$.
