Q. Which of the following transitions involves maximum amount of energy?
A) $M^{-}(g) \rightarrow M(g)$
B) $M(g) \rightarrow M^{+}(g)$
C) $M^{+}(g) \rightarrow M^{2 +}(g)$
D) $M^{2 +}(g) \rightarrow M^{3 +}(g)$
Explanation
(d)
$M^{2 +} \rightarrow M^{3 +}$, after the removal of $2e^{-},$ the nuclear charge per electron increases due to which high energy is required to remove $3e^{-}$
