Expert Answer:

Group 1 metals dissolve in liquid NH3 to give coloured solution because ammoniated electron absorbs energy in the visible region of light and thus imparts blue colour to the solution.

  • The solution is paramagnetic in nature and liberates hydrogen to form amide.
  • The concentrated solution is bronze in colour and diamagnetic in nature.
