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. [1 mark] (c) Explain why atoms do not collapse with reference to the quantum uncertainty principle and with the aid of a sketch. [2 marks] c) Explain two observations with the photoelectric effect that lead to the conclusion that light comes in the form of particles (photons)?

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...

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)

The Bohr model of the hydrogen atom treats electrons as particles that orbit the nucleus at...

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.
