Question

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

Answer 1

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