Match the species in Column-I with their related properties in Column-II

	Column - I		Column - I
i)	$N \left(7\right)$	p)	Paramagnetic
ii)	$C{o}^{2+}\left(27\right)$	q)	Coloured ion
iii)	$M{n}^{2+}\left(25\right)$	r)	Sum of spin $\frac{3}{2}$
iv)	$F{e}^{2+}\left(26\right)$	s)	Magnetic moment$\sqrt{24}$ B,M

$\left(c\right)N\left(7\right)=1S^{2}2S^{2}2P^3$

Paramagnetic due to unpaired electron and sum of spin

$=3\times \frac{1}{2}=1.5$

Thus, $\left(i\right)\to \left(p,r\right)$

$Co\left(27\right)=\left[Ar\right]$ 

$C{o}^{2+}=\left[Ar\right]$   

Paramagentic and coloured due to unpaired sum of spin $=1.5$

Thus, (ii)$\to \left(p,q,r\right)$

$Mn\left(25\right)=\left[Ar\right]4S^{2}3d^6$ 

$M{n}^{2+}\left(25\right)\left[Ar\right]S^{2}3d^5$     

Coloured and aparamagentic

Sum of spin $=2.5$

Thus, $\left(iii\right)\to \left(p,q\right)$

$Fe\left(26\right)=\left[Ar\right]4S^{2}3d^6$ 

$F{e}^{2+}\left(26\right)=\left[Ar\right]3d^6$   

Colored and Paramagnetic

Sum of spin $=2.0$

Magnetic moment $=\sqrt{n\left(n+2\right)}$

 $=\sqrt{4\left(6\right)}$

$=\sqrt{24}BM$

Thus, (iv) $\to \left(p,q,s\right)$
