The diagram to the right shows the lowest four energy levels for an electron in a hypotentical atom. The electron is excited to the `-1` eV level of the atom and transitions to the lowest energy state emitting only two phtosn. Which of the following energies could not belong to either of the phtons?

A

`2 eV`

B

`4 eV`

C

`5 eV`

D

`6 eV`

Text Solution

Verified by Experts

The correct Answer is:
B
Photon energies set `(2eV, 9eV)` & `(6eV, 5eV)`
