Least paramagnetic property is shown by

A

Fe

B

Mn

C

Ni

D

Cu

Text Solution

Verified by Experts

The correct Answer is:
D

`""_(25)M n = [Ar] 3d ^(5) 4s^(2) (n=5)`
`""_(26) Fe= [Ar] 3d^(6)4s^(2)(n=4)`
`""_(28)Ni=[Ar] 3d^(8) 4s^(2)(n=2)`
`""_(29)Cu= [Ar] 3d^(10) 4s^(1) (n=1)`
Hence, maximum paramagnetic is Mn and least paramagnetic is Cu, (paramagnetic character depends on the number of unpaired electrons)
