IB Physics: Activity: Further atomic models

We have a lot of evidence that electrons exist in discrete energy levels but its not good just to say "that"s the way it is" we need a physical model. In 1913 Niels Bohr predicted the energy levels of the hydrogen atom by assuming that the angular momentum of orbiting electrons = nh/2π where n is a whole number (quantum number).The diagram shows an electron in orbit around a Hydrogen nucleus (charge +e).
