Although Cr^(3+) and Co^(2+) ions have same number of unpaired electrons but the magnetic moment of Cr^(3+) is 3.87 BM and that of Co^(2+) is 4.87 BM. Why ?

Find the magnetic moment of Cr^(3+) ion.

(A) Cr^(+3) and Co^(2+) ions have same number of unpaired electrons but the observed magnetic moment of Cr^(3+) is 3.87 B. M and that of Co^(2+) is 4.87 B.M (R) Due to symmetrica electronic configuration there is no orbital motion of unpaired electron in Cr^(3+) ion while appreciable orbital contribution takes place in Co^(2+) ion .

In the Cr^(+2), Mn^(+3), Fe^(+2) and CO^(+3) ions, number of unpaired electrons and magnetic moment wiII be
