Which one of the following will result in an electron transition from the n = 4 level to the n = 7 level in a hydrogen atom?
A)emission of a 0.28 eV photon
B)emission of a 0.57 eV photon
C)absorption of a 0.85 eV photon
D)absorption of a 0.28 eV photon
E)absorption of a 0.57 eV photon

Question

Quizplus · Accepted Answer

According to the equation E = -13.6 eV (1/n^2), the energy difference between the n=4 and n=7 levels is 0.85 eV. Therefore, absorption of a 0.85 eV photon would result in an electron transition from the n=4 to n=7 level. Option E is the only choice that provides the required energy for this transition.
