PLEASE HELP ASAP WITHOUT PUTTING A FILE OR WHATEVER The electron in a hydrogen atom can undergo a transition from n = 6 to n = 1, emitting a photon with energy 2.11 × 10–18 J. (2 points)

i. What is the frequency of this transition?

ii. How does this transition show that the energy of a photon is quantized?

C. Why is it impossible for an electron to have the quantum numbers n = 3, l = 0, ml = 1, ms = + ?
