The depth of the potential well for free electron in a metal can be determined by noting that the photoelectric work function represents the energy necessary to remove an electron in such a state has the Fermi energy. Assuming that each atom contributes one free electron to the gas, calculate the depth of the potential well for free electron in gold. (the work function for gold is 4.8eV)
