Spin only Magnetic Moment

$\text{μ}=\sqrt{\text{n}\left(\text{n}+2\right)}\text{ BM}=1\text{.}73=\sqrt{3}$

$\therefore n=1 \;$(unpaired e^-)

Electronic configuration of$\text{V}={\text{1s}}^{\text{2}}{\text{2s}}^{\text{2}}{\text{2p}}^{\text{6}}{\text{3s}}^{\text{2}}{\text{3p}}^{\text{6}}{\text{3d}}^{\text{3}}{\text{4s}}^{\text{2}}$



to get 1 unpaired electron$\mathrm{V}$has to lose 4 electrons to form${\text{V}}^{4+}.$

So, formula of chloride is${\text{VCl}}_{\text{4}}$
