The Balmer series of hydrogen has a series limit (at 364.6 nm)(see Figure 3.51,Comins,Discovering the Essential Universe,6th ed.)because hydrogen in the n = 2 state:
A) is excited to a higher discrete level by photons shorter than this wavelength.
B) cannot absorb photons of longer wavelength.
C) cannot absorb photons of shorter wavelength.
D) is ionized by photons of shorter wavelength.

Question

Quizplus · Accepted Answer

Photons with wavelengths shorter than 364.6 nm have enough energy to ionize hydrogen atoms in the n = 2 state, removing the electron completely.
