Match the metal ions given in Column-I with the spin magnetic moments of the ions given in Column-II and assign the correct code:

	Column-I		Column-II
A	$C{o}^{3+}$	I	$\sqrt{8}B.M.$
B	$C{r}^{3+}$	II	$\sqrt{35}B.M.$
C	$F{e}^{3+}$	III	$\sqrt{3}B.M.$
D	$N{i}^{2+}$	IV	$\sqrt{24}B.M.$
		V	$\sqrt{15}B.M.$

$C{O}^{3+}=\left[Ar\right]3d^6$  unpaired $e^{-}\left(n\right)=4$ spin magnetic moment $\left(\mu \right)=\sqrt{4(4+2)}=\sqrt{24}B.M$

$C{r}^{3+}=\left[Ar\right]3d^3,$ unpaired $e^{-}\left(n\right)=3$

Spin magnetic moment $\left(\mu \right)$

$\sqrt{3(3+2)}=\sqrt{15}B.M$

$F{e}^{+3}\left[Ar\right]3d^5,$ unpaired $e^{-}\left(n\right)=5$

Spin magnetic moment $\left(\mu \right)=\sqrt{5(5+2)}=\sqrt{35}B.M$

$N{i}^{2+}=\left[Ar\right]3d^8,$ unpaired electron $\left(n\right)=2$

Spin magnetic moment $\left(\mu \right)=\sqrt{2(2+2)}=\sqrt{8}B.M$
