Ammoniated electrons

Vedclass · Answer

(C) When alkali metals dissolve in liquid ammonia,they undergo ionization to form ammoniated cations and ammoniated electrons: $M + (x+y)NH_3 \rightarrow [M(NH_3)_x]^+ + [e(NH_3)_y]^-$. The blue color of the solution is due to the excitation of ammoniated electrons to higher energy levels,which absorb light in the red region of the visible spectrum.

Alkali metals dissolve in liquid ammonia to give a blue-colored solution if it is dilute. This blue color is due to which of the following?
