The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spinn only magnetic moment value of Cr^(3+) ion is "…..........."

Answer»

2.87 B.M.
3.87 B.M.
3.47 B.M.
3.57B.M.

SOLUTION :`CR^(3+)= 3d^(3)` . Hence, `MU = sqrt(n( n+2)) B.M. = sqrt( 3(3+2)) = sqrt( 15) = 3.87 B.M`
