Question

Why do alkali metals in liquid Ammonia act a strong reducing agent

Answer 1

since alkali metals are the elements of group first of the periodic table there outer electronic configuration is ns1 so they tend to lose 1 electrons to achieve the stable noble gas configuration show the act as reducing agent

Answer 2

Alkali metals in liquid Ammonia act as a strong reducing agent because they have a tendency to lose an electron to attain noble gas configuration and stabilize.

Explanation:

The alkali metals which is present in the periodic table belongs to the group 1. They have and outer electronic configuration of $\bold{ns^1}$ which is why they have a tendency to lose one electron and attain stable noble gas configuration.

Besides, an electron is loosely packed in the ammonia solvent cavity that is stabilized by hydrogen bonds.
