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?
Please don't provide handwritten solution .....
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.

A mercury atom is initially in its lowest possible (orground state) energy level. The atom absorbs a photonwith a wavelength of 185 nm and then emits a photon witha frequency of 6.88 × 1014 Hz. At the end of this series oftransitions, the atom will still be in an energy level abovethe ground state. Draw an energy-level diagram for thisprocess and fi nd the energy of this resulting excited state,assuming that we assign a value of E = 0 to the groundstate. (This choice of E = 0 is not the usual convention, butit will simplify the calculations you need to do here.)
1. A mercury atom emits light at many wavelengths, two of which are at (1) 404.7 nm and (2) 435.8 nm . Both of these transitions are to the same final state. Determine the energy of each emitted wavelength (in J).
