If a hydrogen atom in the ground state absorbs a photon of energy 12.09 eV,to which energy state will it make a transition?
A)n = 2
B)n = 3
C)n = 4
D)n = 5

Question

Quizplus · Accepted Answer

The photon's energy of 12.09 eV is equal to the energy difference between the ground state (n=1) and the first excited state (n=2). Therefore, the hydrogen atom will make a transition to the n=2 energy level.
