1)Use the Bohr model to address this question. When a hydrogen atom makes a transition from the 7th energy level to the 2nd, counting the ground level as the first, what is the energy of the emitted photon? Express the answer in electron volts.
2)What is the wavelength, in nanometers, of the emitted photon?
3)What is the radius, in nanometers, of the hydrogen atom in its initial (7th) energy level?
