Magnetic moment $=\sqrt{n(n+2)}$ B.M.

$\mathrm{N}=$ Number of unpaired electron.

(P) ${\mathrm{Mn}}^{+}=[\mathrm{Ar}]4{\mathrm{s}}^{1}3{\mathrm{d}}^5$

| 1 | | 1 | 1 | 1 | 1 | 1 |

$\mu =\sqrt{6(6+2)}=\sqrt{48}\text{ B.M. }$

(Q) ${\mathrm{Cu}}^{+1}=[\mathrm{Ar}]3{\mathrm{d}}^{10}$

$\mu =0\text{ B.M. }$

(R) ${\mathrm{V}}^{+3}=[\mathrm{Ar}]3{\mathrm{d}}^2$

$\mu =\sqrt{2(2+2)}=\sqrt{8}\text{ B.M. }$

(S) ${\mathrm{Co}}^{+3}=[\mathrm{Ar}]3{\mathrm{d}}^6$

$\mu =\sqrt{4(4+6)}=\sqrt{24}\text{ B.M. }$
