The correct order of magnetic moments (spin only) values in BM) among the following is (Atomic number: Mn = 25, Fe = 26, Co = 27)

Magnetic moment is dependent on the number of unpaired electrons in the structure the charge of manganese is 2+ Mn and it has 5 unpaired electrons in its 3d orbital. The charge on Fe is 2+ Co and it has 3 unpaired electrons in its 3d orbital. The charge of manganese is 2+ Fe and it has 0 unpaired electrons in its 3d orbital. Hence, .. 4- 2- 2- 4 4 6 MnCl > CoCl > Fe CN is the correct option.
