$Fe^{3+}$

Vedclass · Answer

(C) To determine the number of unpaired electrons,we look at the electronic configuration of the metal ions:$Cu^{+}$ $(Z=29)$: $[Ar] 3d^{10}$,unpaired electrons = $0$.$Fe^{2+}$ $(Z=26)$: $[Ar] 3d^{6}$,unpaired electrons = $4$.$Fe^{3+}$ $(Z=26)$: $[Ar] 3d^{5}$,unpaired electrons = $5$.$Co^{2+}$ $(Z=27)$: $[Ar] 3d^{7}$,unpaired electrons = $3$.Therefore,the $Fe^{3+}$ ion has the highest number of unpaired electrons,which is $5$.

Which of the metal ion will have the highest number of unpaired electrons?
