Question

Alkali metals are good reducing agents, explain

Answer 1

Alkali metals (Group 1) have an outer electronic configuration as ns1. Due to which the outer electron as the lease attraction with the nucleus.

The energy required to remove a electron is hence less.

Alkali metal is a good reducing agents because of its tendency of donating electron easily.

Answer 2

Alkali metals are good reducing agents because alkali metals have one valence electrons which they lose to attend stability. Hence they themselves undergo oxidation causing reduction of others and are good reducing agents.
