Chapter 20, Problem 2RQ

Interpretation Introduction

Interpretation: The evidence that support putting hydrogen in group $1\text{A}\left(1\right)$ of the periodic table is to be stated. The difference between hydrogen and other group $1\text{A}\left(1\right)$ is to be stated. The valence electron configuration for the alkali metals and properties of the alkali metals is to be stated. The method of preparation of pure metals is to be stated. The formula of the compounds formed when an alkali metal reacts with ${\text{F}}_{\text{2}},\text{S},{\text{P}}_{\text{4}},{\text{H}}_{\text{2}}$ and ${\text{H}}_{\text{2}}\text{O}$ is to be stated.

Concept introduction: Alkali metals are found in group $1\text{A}\left(1\right)$ in the periodic table.

To determine: The evidence that support putting hydrogen in group $1\text{A}\left(1\right)$ of the periodic table; the difference between hydrogen and other group $1\text{A}\left(1\right)$; the valence electron configuration for the alkali metals and properties of the alkali metals; the method of preparation of pure metals; the formula of the compounds formed when alkali metals react with ${\text{F}}_{\text{2}},\text{S},{\text{P}}_{\text{4}},{\text{H}}_{\text{2}}$ and ${\text{H}}_{\text{2}}\text{O}$.
