1. Explain what is happening to electrons when light is emitted in emission spectra.
2. List the possible energy level changes for electrons emitting visible light in the hydrogen atom. What is the name of this series of lines?
3. Why is it not possible for us to see light emitted from hydrogen atoms when electrons fall either to the ground state or to the third energy level?What are the names of these series of lines?
4. Hydrogen atom electrons emit photons when the fall from higher energy levels to blower energy levels. For the n=4---1 transition, a) calculate the energy change. b) convert the energy to wavelength, and c) identify its place in the electromagnetic spectrum.
