Question

Describe how are alkali and alkaline earth metals good reductants?

Answer 1

Alkali metal are very reactive and can displace metals of lower reactivity from their compounds

Answer 2

Alkali and alkaline earth metals have high reduction potentials. Hence, they are very strong reducing agents. Hence, other reducing agents cannot reduce oxides or other compounds of alkali and alkaline earth metals. Hence, chemical reduction is not possible.
