Although Cr^(3+) and Co^(2+) ions have same number of unpaired electrons but the magnetic moment of Cr^(3+) is 3.87 B.M and that of Co^(2+) is 4.87 B.M. Why? |
| Answer» Solution :In `CR^(3+)` there is no orbital CONTRIBUTION because of SYMMETRICAL configuration while in `CO^(2+)`, the orbital contribution is present SIGNIFICANTLY | |
