Question
The diagram shows the four energy levels of an electron in the Bohr model of the hydrogen atom. Identify the transition in which the emitted photon will have the highest energy.
Options
I
II
III
IV
Solution
I
Explanation:
The correct scale is used to create the energy diagram, which displays the various energy levels.
The largest energy difference occurs during the change from state 3 to state 1. The first jump would be the most energetic and provide the strongest photon emission.
