(a) Using the Bohr model, calculate the speed of the electron in a hydrogen atom in the n = 1,2 and 3 levels.
(b) Calculate the orbital period in each of these levels.
(c) The average lifetime of the first excited level of a hydrogen atom is 1.0 x 10-8 s. In the Bohr model, how many orbits does an electron in the n = 2 level complete before returning to the ground level?
