Q. Correct order of paramagnetic character is :-

NTA AbhyasNTA Abhyas 2022

Solution:

Greater is the number of unpaired electrons, greater is the paramagnetic character.
$Cr-\left[\right.Ar\left]\right.4s^{1}3d^{5}n=6$
$Fe-\left[\right.Ar\left]\right.4s^{2}3d^{6}n=4$
$Zn-\left[\right.Ar\left]\right.4s^{2}3d^{10}n=0$
$Mn-\left[\right.Ar\left]\right.4s^{2}3d^{5}n=5$
Order of paramagnetic character among following elements $Cr>Mn>Fe$
