Write a balanced equation for the formation of ammoniated IIA metal ions form the metals in liquid ammonia?

Explanation

Alkaline earth metals dissolve in liquid ammonia to give deep blue black solutions forming ammoniated ions.
`M+(x+y) NH_3 to [M(NH_3)_x]^(2+) +2[ e(NH_3)_y]^-`
For the above solutions, ammoniates `[M(NH_3)_x]^(2+)` can be recovered.
