According to the Bohr model of the hydrogen atom, which of the following statements are TRUE? I. As the electron obits the proton, it constantly radiates light with a frequency equal to its frequency of revolution. II. The electron orbits the proton in certain orbits that can be found by assuming that its angular momentum is quantized. III. Because of the quantization of angular Page 4 momentum, calculations using the Bohr model and those based on classical physics can never give the same result. IV.
