An electron in a Hydrogen atom originally at n=5
energy level absorbs a photon with a frequency of 6.54×10^13 and
then proceeds to emit another photon with a frequency of
2.98×10^14. To what energy level does the electron move?
a) Find the energy of an electron in the n=5 state of the hydrogen atom. b) Find the energy of an electron in the n=6 state of the hydrogen atom. c) If an electron initially in the n= 6 state falls to the n= 5 state, how much energy must the electron give up? d) If an electron initially in the n= 6 state falls to the n=5 state, what is the wavelength of the photon that will be emitted?
Suppose a photon is absorbed by the electron in a hydrogen atom
in an n= 2 state. What wavelength should the photon have to enable
the electron to transition to the n= 4
state? Once the photon is absorbed, what are the various
wavelengths of photons that could be emitted by the atom? (Use Bohr
approximation).
An electron (in a hydrogen atom) in the n=5 state drops
to the n=2 state by undergoing two successive
downward jumps. What are all possible combinations of the resulting
photon wavelengths?
If a single electron in an excited hydrogen atom is
occupying the 3rd energy level and then relaxes back to
the ground state, how much energy is released in the form of
electromagnetic radiation?
Spectral Absorption and Emission
Consider a hydrogen atom with an electron initially in the n = 4
state.
a) List the 3 different wavelengths that could be observed in
the emission spectrum for this atom given the electron begins in
level n = 4.
b) What is the longest wavelength photon that could potentially
be absorbed by the electron in the level n = 4?
c) How much energy would be required to ionize this atom?
d) What is the...

b. As the atom relaxes, the electron transitions to the ground
state. What is the energy of the photon released during the
electron transition?
