M2+ longrightarrow M3+, after the removal of 2 e-, the nuclear charge per electron increases, due to which high energy is required to remove 3 e-.

Q. Which of the following transitions involves maximum amount of energy?

$M^{-} (g) ⟶ M (g)$

$M^{-} (g) ⟶ M^{+} (g)$

$M^{+} (g) ⟶ M^{2 +} (g)$

$M^{2 +} (g) ⟶ M^{3 +} (g)$

$M^{2 +} ⟶ M^{3 +}$ , after the removal of $2 e^{-}$ , the nuclear charge per electron increases, due to which high energy is required to remove $3 e^{-}$ .

Q. Which of the following transitions involves maximum amount of energy?

M−(g)⟶M(g)

M−(g)⟶M+(g)

M+(g)⟶M2+(g)

M2+(g)⟶M3+(g)

M2+⟶M3+, after the removal of 2e−, the nuclear charge per electron increases, due to which high energy is required to remove 3e−.

$M^{-} (g) ⟶ M (g)$

$M^{-} (g) ⟶ M^{+} (g)$

$M^{+} (g) ⟶ M^{2 +} (g)$

$M^{2 +} (g) ⟶ M^{3 +} (g)$

$M^{2 +} ⟶ M^{3 +}$ , after the removal of $2 e^{-}$ , the nuclear charge per electron increases, due to which high energy is required to remove $3 e^{-}$ .
