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)

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state

An electron in a hydrogen atom is excited from the n = 1 ground state to the n = 4 excited state. Classify the statements about this absorption and emission process as true or false. True On average, the electron is closer to the nucleus in the n = 4 state than in the n = 1 state. The wavelength of light absorbed when the electron is excited from the ground state to n = 4 is the same as the wavelength of...

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...

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....
