Chemistry Question on Classification of elements & periodicity in properties

Which of the following transitions will involve maximum amount of energy?

A

M→M++e−M \to M^+ + e^-

B

M−→M++2e−M^- \to M^+ + 2e^-

C

M2+→M3++e−M^{2+} \to M^{3+} + e^-

D

M+→M2++e−M^+ \to M^{2+} + e^-

Answer

M2+→M3++e−M^{2+} \to M^{3+} + e^-

Explanation

Solution

M2+→M3++e−M^{2+} \to M^{3+} + e^- ; IE3>IE2>IE1IE_3 > IE_2 > IE_1
