(i) Alkali and alkaline earth metals are themselves strong reducing agents. Therefore, these metals cannot
be obtained by chemical reduction of their oxides and other compounds.
(ii) These metals are highly electropositive in nature. So, these cannot be displaced from the aqueous solutions of their salts by other metals.
