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+)` `4.87` B.M. because….

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 ?

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 ?

(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 .

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

The magnetic moment of Cr(Co)_6 is _________BM

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