For a specific element, photons of how many different energies could be emitted by electrons in the n = 3 level as they return to the n = 1 level?
A) 1
B) 4
C) 2
D) 3

Question

Quizplus · Accepted Answer

Electrons in the n=3 level can transition directly to n=1, or they can transition to n=2 and then to n=1. This results in three possible photon energies: n=3 to n=1, n=3 to n=2, and n=2 to n=1.
