A)that start in the n = 2 level.
B)that end up in the n = 2 level.
C)that end up in the n = 3 level.
D)that end up in the ground state.
E)that start in the ground state.

Question

Quizplus · Accepted Answer

The four visible lines emitted by hydrogen atoms are produced when electrons transition from higher energy levels to the n = 2 energy level. Specifically, each line corresponds to a transition from a higher level (n = 3,4,5,6) down to the n = 2 level. Therefore, option B (electrons that end up in the n = 2 level) is the best choice.
