Question

By giving chemical reaction show that alkali metals and hydrogen both are reducing agent??

Answer 1

Dear student,

Alkali metals are soft because of their large atomic radii. They have the largest atomic volume and the smallest atomic mass in their period. This makes their atomic density least in the period and thus they are very soft.

Alkali metals have very low ionization energy and thus they are oxidised very easily and act as very strong reducing agents.

CuO + H ₂ →→ Cu + H ₂ O
Hydrogen gains an electron and is oxidised. Thus it is the reducing agent.
