Chapter 20, Problem 3RQ

Interpretation Introduction

Interpretation: The valence electron configuration for alkaline earth metals and their common properties are to be stated. The preparation methods of alkaline earth metals are to be stated. The formulas of the compounds formed when an alkaline earth metals reacts with the given elements is to be predicted.

Concept introduction: Alkaline earth metals are highly reactive metals. They form ionic compound by losing two valence electrons and contains ${\text{M}}^{2+}$ cation.

To determine: The valence electron configuration for alkaline earth metals and enlist their common properties; the preparation methods of alkaline earth metals; the formulas of the compounds formed when an alkaline earth metals reacts with ${\text{F}}_{\text{2}},{\text{O}}_{\text{2}},\text{S,}{\text{N}}_{\text{2}},{\text{H}}_{\text{2}}$ and ${\text{H}}_{\text{2}}\text{O}$.
