Question

What is the valence electron configuration for alkaline earth metals? List some common properties of alkaline earth metals. How are alkaline earth metals prepared?

Short answer

$n{s}^2$; electro-positive, ions, strong reducing agents; electrolytic reduction of molten chlorides are the valence electron and properties and alkaline earth metals are prepared.

Step-by-step solution

Definition of alkaline earth metals:

Densities are rather modest, in terms of metals, they have relatively low melting and boiling points, typically ductile and malleable, with a complete outer electron shell and two electrons in the outer shell, Electron affinities are low, Electro- negativities are low are the properties of alkaline earth metals.

Determination of alkaline earth metals:

The valence electron configuration of alkaline earth metals has an $n{s}^2$.In comparison to alkali metals, alkaline earth metals are less electropositive and reactive. The alkaline earth metals, with the exception of beryllium, which mimics aluminium in certain ways, have chemical characteristics that are comparable to those of aluminium.The oxidation number of alkaline earth metals in the combined state is generally invariably +2 , since their $M^{2+}$ions achieve the stable electron configuration of the preceding noble gas.

The alkaline earth metals are excellent reducers.

Each element forms oxide by reducing $O^2$ in the air. Except for and , which create oxide coatings that stick to the surface. At ambient temperature, alkaline earth metals convert $H_{2}O$ to create $H_2$. Electrolytic reduction of their molten chlorides yields pure alkaline earth metals. Therefore, the valence electron and characteristics of alkaline earth metals are prepared via electrolytic reduction of molten chlorides.
