Transition metals and many of their comp...

Transition metals and many of their compounds show paramagnetic behaviour where there are unpaired electron or electrons. The magnetic moment arises from the spin and orbital motions in ions or molecule. Magnetic moment of n unpaired electrons is given as
`mu=sqrt(n(n+2))` Bohr magneton
Magnetic moment increases as the number of unpaired electrons increases.
Q. In 3d series the maximum magnetic moment is shown by

A

Sc

B

V

C

Cr

D

Fe

Text Solution

Verified by Experts

The correct Answer is:
c
Cr-atom has maximum number of unpaired electrons i.e., 6. Hence, the magnetic moment is
`sqrt(6xx8)=sqrt(48)BM`
