Which of the following electronic configurations in the outermost two shells is characteristic of the alkaline earth metals?
An alkaline earth metal.
The compounds of alkaline earth metals have the following magnetic nature:
Alkali and alkaline earth metals along with hydrogen and helium constitute s-block elements. They have low ionization enthalpies and hence exhibit characteristic flame colourations. They have highly negative electrode potentials and hence are strong reducing agents. Their solutions in liquid ammonia are conducting and also act as strong reducing agents. Being stronger reducing agents than hydrogen, they are usually prepared by electrolysis of their fused chlorides. Their oxides are basic and the basic strength increases down the group. The solubility of carbonates and sulphates of alkali and alkaline earth metals show opposite trends. The carbonates of alkaline earth metals and lithium carbonate decompose on heating while the carbonates of other alkali metals do not decompose on heating The bicarbonates of both alkali and alkaline earth metals on heating give carbonates.
Which of the following processes is used in the extractive metallurgy of magnesium?
