Which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photon?

A

`3s`

B

`2P`

C

`2S`

D

`1S`

Text Solution

Verified by Experts

The correct Answer is:
D
`(1)/(lambda)=R_(H)[(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
In balmer series, electron jumps higher energy level to `2nd` energy level. Hence third line form when electron jump fifth energy level to 2 energy level. `5rarr2`
