Which of the following transitions involves maximum energy?
(1) `M^(-) (g) to M(g)`
(2) `M^(2+) (g) to M^(3+) (g)`
(3) `M^(+) (g) to M^(2+) (g)`
(4) `M(g) to M^(+) (g)`

Text Solution

Verified by Experts

The correct Answer is:
2
`IE_(3) gt IE_(2) gt IE_(1)`
Hence `M^(2+) to M^(3+)`. i.e, is maximum
