Which of the following transitions involves maximum amount of energy?A. `M^(-)(g)toM(g)`B. `M(g)toM^(+)(g)`C. `M^(+)(g)toM^(2+)(g)`D. `M^(2+)(g)toMg^(3+)(g)`

Answer» Correct Answer - D
`M^(2+) to M^(3+)` , after the removal of second electron, the nuclear charge per electron increases, due to which high energy is required to remove the 3rd electron
