Why is the solution of an alkali metal in ammonia blue?

The alkali metals dissolve in ammonia to give a deep blue solution which is cnducting in nature. M+(x+y)NH_(3)to[M(NH_(3))_(x)]^(2+)+2[e(NH_(3))_(y)]^(-) which of the followin is not true about the solutions of alkali metals in liquid ammonia?

Which of the following statements is not ture about the dilute solutions of alkali metals in liquid ammonia ?

The alkali metals

The alkali metals

In the following questions , a statement of assertion (A) is followed by a statement of reason (R). Br A: Dilute solutions of alkali metal in liquid ammonia are paramagnetic in nature R: Formation of ammoniated cations takes place when alkali metals dissolve in ammonia.

Why are the solutions of alkali metal atoms in liquid ammonia blue coloured and highly conducting?

the concentrated solution of alkali metals in liquid ammonia becomes blue due to

Which of the following statements is wrong for the solution of alkali metals in liquids ammonia

All alkali metals dissolve in anhydrous liquid ammonia to give blue colour solution. It is the ammoniated electron which is reponsible 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 electron, [e(NH_(3))_(y)]^(-) , value of x and y depend on the extent of solvation by NH_(3) . Dilute solutions are paramagnetic due to free ammoniated electrons. Q. Which of the following statement about solution of alkali metals in liquid ammonia is correct?

Statement-1: 3M solution of alkali metal in liquid ammonia has copper bronze colour. Statement-2: copper bronze colour is due to the formation of metal cluster.
