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 initially in the n=2 state of a hydrogen atom is
excited by a photon to the n=5 state.
a. What is the energy of the excitatoin photon?
b. As the atom relaxes, the electron transitions to the ground
state. What is the energy of the photon released during the
electron transition?
c. What is the frequency of the released photon?
d. What is the name of the scientist who first modeled the atom
as a miniature solar system?
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?
An electron in the hydrogen atom falls from the 2p to 1s state and a photon is emitted. What is the wavelength of the emitted photon (in nm)?
Select one:
a. 20
b. 91
c. 122
d. 364
e. 138
Calculate the energy (J) of the photon emitted when an electron
in the hydrogen atom falls from n=5 to n=2 .
Use 2.178 x 10-18 J for the constant in the Bohr
equation.
Answer should be in scientific notation, e.g.
3000 = 3E3
I have no idea how to get this problem help me!!
A ground state hydrogen atom absorbs a photon of light having a
wavelength of 93.03 nm. It then gives off a photon having a
wavelength of 93 nm. What is the final state of the hydrogen
atom?
nf= ?
A hydrogen atom emits a photon when its electron falls from its
3rd excited state (?=4) to its first excited state (?=2).
Another electron in a box with sides of infinite potential
absorbs the photon and jumps from the ground state (?=1) to the 5th
excited state (?=6).
a. [2] What is the wavelength of the
emitted photon? (Calculate this, don’t just look it up)
b. [3] What is the length of the
box?
c. [3] Using the fact that...
