Vedclass · Answer

(D) The electronic configurations and number of unpaired electrons are as follows:$Mg^{2+} (Z=12): 1s^2 2s^2 2p^6$,Number of unpaired electrons = $0$.$Ti^{3+} (Z=22): [Ar] 3d^1$,Number of unpaired electrons = $1$.$V^{3+} (Z=23): [Ar] 3d^2$,Number of unpaired electrons = $2$.$Fe^{2+} (Z=26): [Ar] 3d^6$. In $3d^6$,there are $4$ unpaired electrons (one orbital has $2$ electrons,four orbitals have $1$ electron each).Therefore,$Fe^{2+}$ has the maximum number of unpaired electrons.

Which of the following has the maximum number of unpaired electrons?
