Which of the following transitions involves maximum amount of energy?

Options

  1. AM⁻(g) M(g)
  2. BM⁻( g ) M⁺(g)
  3. CM⁺(g) M²⁺(g)
  4. DM²⁺( g ) M³⁺( g )

Correct answer

D. M²⁺( g ) M³⁺( g )

Step-by-step solution

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