(d) No of unpaired electron in different ion are as under

$M{g^{2 + }} 	o 1{s^2},2{s^2}2{p^6},3{s^0} = 0$

$T{i^{3 + }} 	o 1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^1},4{s^0} = 1$

${V^{3 + }} 	o 1{s^2},2{s^2}2{p^6},3{s^2}3{p^6}3{d^2},4{s^0} = 2$

$F{e^{2 + }} 	o 1{s^2},2{s^2}s{p^6},3{s^2}3{p^6}3{d^6},4{s^0} = 4$
