Bohr theory of the atom:
In the hydrogenic Bohr orbit of quantum number n compute the ratio of the circumference of the orbit to the wavelength of the electron. Provide an interpretation of this result in terms of the concepts of de Broglie.
Treating the Bohr orbit as a circulating electrical current, compute the magnetic moment of the electron in a Bohr orbit of quantum number n (Hint: use Ampere’s law). What is the ratio between the magnetic moment and the angular momentum?

An electron in a hydrogen atom undergoes a transition from an orbit with quantum number ni to another with quantum number nf.
An electron in a hydrogen atom undergoes a transition from an orbit with quantum number ni to another with quantum number nf. Vi and Vf are respectively the initial and final potential energies of the electron. If Vi/ Vf = 6.25, then the smallest possible nf.

In the Bohr model, when an electron leaves one n orbit and
enters another n orbit, a photon is either emitted or absorbed.
Derive a relationship between the wavelength of the emitted or
absorbed photon and the change in the DeBroglie wavelength of the
electron when it moves from one n to another n.

The Bohr model of the hydrogen atom treats electrons
as particles that orbit the nucleus at a particular radius and with
a particular speed. This model correctly predicts the energy
levels of the hydrogen atom, but paints an inaccurate physical
picture of the atom. Explain how the real hydrogen atom
differs from the Bohr model.

3. Prior to quantum mechanics the Bohr Model viewed the atom as
having electrons traveling in circular orbits (shells) about the
positively charged nucleus. This model gives a reasonable estimate
of the dipole moment of the hydrogen atom if one assumes the radius
of the electron orbit about the nucleus is 5.3 x 10-11 m. Using the
Bohr Model

the hydrogen atom in a magnetic field, B, with...
