The
hydrogen atom electron is in the ground state. The electron absorbs
energy and makes a transition to the n=3 state. Then it returns to
the ground state by emitting two photons when going to n=2 and then
n=1 states.
A. What are the wavelengths of these photons?
B. What will be the wavelength if only one photon is
emitted?
C. What is the maximum number of electrons with ml=3 in the
shell with n=5?
