$\mathrm{T}{\mathrm{i}}^{3+}\hspace{0.33em}\to \hspace{0.33em}3{\mathrm{d}}^{1}4{\mathrm{s}}^0$;$\mathrm{S}{\mathrm{c}}^{3+}\hspace{0.33em}\to \hspace{0.33em}3{\mathrm{d}}^0$;$\mathrm{M}{\mathrm{n}}^{2+}\hspace{0.33em}\to \hspace{0.33em}3{\mathrm{d}}^{5}4{\mathrm{s}}^0$;$\mathrm{Z}{\mathrm{n}}^{2+}\hspace{0.33em}\to \hspace{0.33em}3{\mathrm{d}}^{\text{10}}4{\mathrm{s}}^0$

In$\mathrm{M}{\mathrm{n}}^{2+}$number of unpaired d${\mathrm{e}}^{-}=5$. So it has maximum magnetic moment according to the formula.$\mathrm{\mu }=\sqrt{\mathrm{n}(\mathrm{n}+2)}$
