Question

Alkali metals are powerful reducing agents

Answer 1

As the alkali metals have low ionization energies for removal of their single valence electron, they are powerful reducing agents – they cause electron gain in substances they react with. Compounds of d-block elements are frequently paramagnetic.

i hope this answer helps..

mark me as a brainliest..

Answer 2

Alkali metals are powerful 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.
