In no more than one page, describe the Bohr model of the atom,
the assumptions is it based on, and how it relates to the
characteristic emission spectra from discharge tubes containing
atoms such as sodium neon. You may include diagrams.

Describe the Bohr model of the hydrogen atom with the aid of a
sketch and an equation for the allowed state energies for which the
ground state energy is -13.61 eV. Define all variables used. [2
marks] (b) De Broglie’s equation defines a wavelength for a
particle, yet in the view of quantum mechanics, matter is in the
form of particles and not waves. Explain how this apparent paradox
is resolved by carefully defining the variables in de Broglie’s
equation....
Describe the Bohr model of the Hydrogen atom in detail. Take
into account the following points:(a) Explain its significance and prediction.(b) How does the Bohr model explain the spectrum of the Hydrogen
atom.(c) Explain the shortcomings of this model.
1.With the aid of a labeled diagram, describe the Bohr model of
the hydrogen atom.
2. Derive the following relationship for a hydrogen atom
according to the Bohr model: rn = a n 2 where rn are the permitted
radii of the electron orbit, n = 1, 2, 3…, and ‘a’ is a constant.
Determine ‘a’ in terms of variables that you define. Hint: equate
Coulomb’s law with the centripetal force acting on an electron, and
then take angular momentum...
The Bohr model of the atom was an early attempt, by Danish
theoretical physicist Niels Bohr in 1913, to understand the
properties of atoms by incorporating the wavelike nature of
electrons into an otherwise classical description. The basic
assumptions of the model are:
a. An electron in an atom moves in circular orbits about a
positively charged nucleus, with the Coulomb attraction providing
the centripetal force.
b. Since electrons are waves, an electron may only (stably)
orbit the nucleus at...
Answer the following questions using the Bohr model of the
hydrogen atom.
a) A hydrogen atom is the n = 3 excited state when its electron
absorbs a photon of energy 4.40 eV. Draw a diagram roughly to
scale, of relevant energy levels for this situation. Make sure to
show and label the initial energy of the H atom in the n=3 state,
the energy level at which this atom loses its electron, and kinetic
energy of the electron.
b)What...
In the "Bohr model" of the Hydrogen atom, a single electron is
said to have a circular orbit around the nucleus (in this case
consisting of a single proton), analogously to how the Earth orbits
the Sun. If the electron orbits at a distance of
1.5�10-10 m, What is the electric force felt by the
electron? What speed must the electron have in order to
maintain its orbit? ( in mi/hr and m/s)
