Question

why S block elements are strong reducing agent

Answer 1

Due to low ionisation ethalpy of metals, s-block elements ( both alkali and alkaline earth metals) are good reducing agents.


Alkali metals are soft because of their large atomic radii. They have 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.

Answer 2

Alkali metals strong reducing agents. Ans: The process of addition of electrons is called reduction and element that gives electrons(s) is called reducing agent. During reactions alkali metals redely gives their valence electron, thus these metals are considered as strong reducing agents.
