The magnetic moment is associated with its spin angular momentum and orbital angular momentum. Spin only magnetic moment value of Cr3+ ion is ___________.
Electronic configuration of Cr3+ is [Ar]3d3. The number of electrons that contribute towards spin only magnetic moment are 3. Spin only magnetic moment can be calculated using this formula
Where n is the number of unpaired electrons. So for Cr3+ , the number of unpaired electrons equals 3.
= 3.87 B.M
