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

A

`3 s`

B

`2 p`

C

`2 s`

D

`1 s`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) 1 s-orbital is of lowest energy. Absorption of photon can raise the electron in higher energy state but emission is not possible.
