Chapter 4, Problem 4.11QP

(a)

Interpretation Introduction

Interpretation: the outer electron configurations for the alkali metals, alkaline earth metals, halogens and noble gases should be given.

Concept Introduction:

• The elements with same valence electrons have similar properties and are placed in the same group in periodic table.
• Group I, II, VII, and VIII in the periodic table contains 1, 2, 7 and 8 valence electrons respectively.
• The outer electronic configuration of alkali metals, alkaline earth metals, halogens and noble gases is ${\text{ns}}^{\text{1}}$, ${\text{ns}}^2$, ${\text{ns}}^{\text{2}}{\text{np}}^5$ and ${\text{ns}}^{\text{2}}{\text{np}}^6$ respectively.

To find: the outer electron configurations for the alkali metals.
