Which of the following ions exhibits the largest magnetic moment?

The electronic configurations are ${ }_{23}{\mathrm{V}}^{3+}\left(3\mathrm{d}{)}^2{;}_{24}{\mathrm{Cr}}^{3+}\right(3\mathrm{d}{)}^3{;}_{26}{\mathrm{Fe}}^{3+}(3\mathrm{d}{)}^5$ and ${ }_{27}{\mathrm{Co}}^{2+}(3\mathrm{d}{)}^7$Maximum unpaired electrons is possessed by ${\mathrm{Fe}}^{3+}$ ions. Hence, this will exhibit maximum magnetic moment.
