Question

A hydrogen atom makes a transition from a n=3 state to a n= 2 state (the Balmer Hα line) while in a magnetic field in the + z - direction and with magnitude 1.50 T . If the magnetic quantum number is ml=2 in the initial (n= 3) state and ml=1 in the final (n= 2) state, by how much is the initial energy level shifted from the zero-field value? By how much is the final energy level shifted from the zero-field value? By how much is the wavelength of the Hα line shifted from the zero-field value

A hydrogen atom (Z=1) is in the third excited state. It makes a
transition to a different state, and a photon is either emitted or
absorbed. Answer the following conceptual questions:
What is the quantum number of the third excited state?
When an atom emits a photon, is the final quantum number of the
atom greater than or less than the initial quantum number?
When an atom absorbs a photon, is the final quantum number of
the atom greater than...

Consider the electronic transition from n = 4 to n = 1 in a
hydrogen atom, and select the correct statement below: A photon of
97 nm wavelength and 2.05x10-18 J energy was emitted from the
hydrogen atom in this electronic transition. A photon of 97 nm
wavelength and 2.05x10-18 J energy was absorbed by the hydrogen
atom in this electronic transition. A photon of 122 nm wavelength
and 1.64x10-18 J energy was emitted from the hydrogen atom in this...

Part A: If a electron in a hydrogen atom makes a transition from
ground state to n = 8 level what wavelength of light in (nm) would
be needed for the abosorbed photon to cause the transition?
Part B: If the same electron falls to a lower level by emmitting
a photon of light in the Paschen series what is the frequncy of
light in (Hz) thats emitted?
(2) When a photon have a wavelength of 195nm strikes the...

A hydrogen atom transitions from the n = 6 excited state to the
n = 3 excited state, emitting a photon.
a) What is the energy, in electron volts, of the electron in the
n = 6 state? How far from the nucleus is the electron?
b) What is the energy, in electron volts, of the photon emitted
by the hydrogen atom? What is the wavelength of this photon?
c) How many different possible photons could the n = 6...

A hydrogen atom, initially in the 3s state, is placed in a
0.800-T magnetic field that points in the +z￼-direction. If the
atom emits a photon, what are the possible photon energies? What
are the initial and final ￼m_l values for the transition that
produces a photon with the shortest wavelength?

An electron in the d energy state level of a hydrogen atom is
placed in an external magnetic field. It is observed that a photon
of energy 1968 μeV is emitted when the electron transition from the
maximum to the minimum energy state.

An electron in a hydrogen atom undergoes a transition from the n
= 6 level to some lower energy level. In doing so, energy is
released in the form of light. a) Calculate the frequency in s-1
(to 3 significant figures) of a photon of light associated with the
highest frequency transition (i.e. largest difference in frequency)
possible from the n = 6 to a lower level. (HINT: Try drawing a
picture first…) b) Calculate the wavelength (in nm) of...

For the 3d state (orbital) of the hydrogen atom, the principal
