Toppr Admin · Accepted Answer

V3- has 3d2 outer electronic configuration with 2 unpaired electrons- Ni2-xA0- has 3d8 outer electronic configuration with 2 unpaired electrons- Thus- V3- and-xA0- Ni2- have same number of unpaired electrons-

Which of the following ions has same number of unpaired electrons as those present in V3+ ion?Fe3+Mn2+Ni2+Cr3+

V3+ has 3d2 outer electronic configuration with 2 unpaired electrons. Ni2+ has 3d8 outer electronic configuration with 2 unpaired electrons. Thus, V3+ and Ni2+ have same number of unpaired electrons.

${F e}^{3 +}$
${M n}^{2 +}$
${N i}^{2 +}$
${C r}^{3 +}$

$V^{3 +}$ has $3 d^{2}$ outer electronic configuration with 2 unpaired electrons. ${N i}^{2 +}$ has $3 d^{8}$ outer electronic configuration with 2 unpaired electrons. Thus, $V^{3 +}$ and ${N i}^{2 +}$ have same number of unpaired electrons.
