For a hydrogen atom,which electronic transition would result in the emission of a photon with the highest energy?
A)2s → 3p
B)2p → 6d
C)4p → 2s
D)5f → 3d

Question

Quizplus · Accepted Answer

The energy of a photon is directly proportional to the difference in energy between the two energy levels involved in the electronic transition. According to the Bohr model of the hydrogen atom, an electron in the 4th energy level (4p) has a higher energy compared to an electron in the 2nd energy level (2s). Therefore, the transition from 4p to 2s would result in the emission of a photon with the highest energy. The other choices involve either higher level energy states that are not allowed or very low energy differences resulting in low-energy photons.
