When sodium metal is dropped in liquid `NH_(3)` it forms `Na^(+)` and gets ammoniated.following forces are responsible for the formation of ammoniated sodium ion

Sodium reacts with liquids NH_(3) to produce.

When sodium formate is heated with soda lime, it forms:

Dilute solutions of alkali metals in liquid NH_(3) are blue. It is the ammoniated electron which is responsible for the blue colour of the solution, and the electrical conductivity is due to the ammoniated cation, [M(NH_(3))_(x)]^(+) as well as the ammoniated electrons, [e(NH_(3))_(y)]^(-) , values of x and y depend on the extent of solvation (by NH_(3) ). Dilute solutions are paramagnetic due to free electrons. What happens if alkali metals is allowed to react with concentrated liquid ammonia?

When a piece of sodium metal is dropped in water, hydrogen gas evolved because
