Question

Experimental value of magnetic momentum of ${Mn}^{2+}$ complex is $5.96$ B.M. This indicates:

• A. Axial and orbital motion of electron in same direction
• B. Axial and orbital motion of electron in opposite direction
• C. Electron does not exhibit orbital motion, it only exhibits axial motion
• D. Electron does not exhibit axial motion, it only exhibits orbital motion

Answer 1

The correct option is A Axial and orbital motion of electron in same direction

$\sqrt{n(n+2)}=5.96$
$n=5$
The axial motion of electron is clockwise because $S=+1/2$ and the orbital motion will also be in clockwise direction.
