On emitting a photon, the hydrogen atom recoils to conserve
momentum. Explain the fact that the energy of the emitted photon is
less than the energy difference between the
A hydrogen atom
(Z = 1)
is in the fourth excited state, and a photon is either emitted
or absorbed.
Concepts:
(i) What is the quantum number of the fourth excited state?
12 345
(ii) When an atom emits a photon, is the final quantum number
nf
of the atom greater than or less than the initial quantum
number ni?
greater thanless than
(iii) When an atom absorbs a photon, is the final quantum
number
nf
of the atom greater than...
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).
a. A relatively rare transition of the hydrogen atom emits a
radio photon with with ? = 21 cm. This emission line is extremely
important to astronomers for two main reasons: it cuts through most
gas and dust without being absorbed and, although transition is
rare, there is so much hydrogen in space that the 21 cm photons are
themselves quite common. Suppose that one such photon from a
distant galaxy is measured to have a wavelength of just 11...
a hydrogen atom in the ground state absorbs a photon
of light with a wavelength of 97.3nm causing the electron to jump
to an unknown energy level. the electron then relaxes emitting a
photon of light in the visible range, what is the wavelength of the
emitted photon?
(A) Is it possible for a photon to emerge when a bound Hydrogen
atom changes its state from n = 6, ell = 3 to n = 3, ell = 2? If
not, explain.
(B) Is it possible for a photon to emerge when a bound Hydrogen
atom changes its state from n = 3, ell = 2 to n = 6, ell = 3? If
not, explain.
(C) Is it possible for a photon to emerge when a bound...
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?

as a miniature solar system?
A hydrogen atom has an angular momentum of According to the Bohr
model, determine:
A) The number of the orbit (main quantum number)
B) The energy (eV) associated with this state.
C) The radius of this orbit.
D) The speed of the electron associated with this orbit.
e) If a transition occurs from this state to the base state (n =
1), what is the energy that the photon has during the
transition?
f)). What is the wavelength of the...
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!!
