16) In qualitative terms, how does Bohr's model account for the atomic spectrum of hydrogen? More than one selection may be correct. a) When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron stays in the orbit having n = 1. b) The energy released when an electron drops from a higher to lower orbit appears as a photon with the appropriate frequency. c) The energy released when an electron drops from a higher to lower orbit appears as a photon with energy equal to the energy difference between the two orbits. d) Electrons are found in orbits of arbitrary energy. e) The energy released when an electron drops from a higher to lower orbit appears as a photon with an arbitrary frequency. f) Electron moves around the nucleus along orbits. g) When a hydrogen atom absorbs energy, as it does when an electric discharge passes through it, the electron is raised from the orbit having n = 1 to a higher orbit, to n = 2 or n = 3 or even higher.

Consider a helium ion with one electron in the ground state. It turns out that it would take about 28 eV to remove this electron through ionization. Blue photons have an energy of about 4 eV. Can this electron emit about 7 blue photons. Is this true? Why or why not?
The Balmer series provided the clue to the structure of the hydrogen atom, the simplest atom with only one electron. From that we learned about the structure of all atoms, even those more complex than uranium with its 92 electrons, the heaviest of the natural elements. This series ends on the lowest energy state with n=2 and starts with any state above it. The first line of the Balmer series arises when the atom changes from a state with n=3 to one with n=2. The second line comes from the change from n=4 to n=2, and so on. 3. Suppose that you could measure accurately the wavelengths of the first two lines of the Balmer series. How could you use those measurements to predict the wavelength of the first line of the Paschen series, the ones ending on n=3? This is the method by which we measure the energy levels of atoms experimentally.
