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

Question

Quizplus · Accepted Answer

The energy of a photon emitted during an electronic transition is directly proportional to the difference in energy between the two energy states involved in the transition. The electronic transition from 4p to 2s involves the largest energy difference and therefore results in the emission of a photon with the highest energy.
