The work function (binding energy) is the energy that must be supplied to cause the release of an electron from a photoelectric material. The corresponding photon frequency is the threshold frequency. The higher the energy of the incident light, the more kinetic energy the electrons have in moving away from the surface. The work function for cerium (used increasingly in the manufacture of cell phones) is equivalent to 280.0 kJ/mol photons. Use this information to calculate the energy, wavelength, and velocity of ejected electrons. What is the kinetic energy, in Joules, of each ejected electron when light of 211.0 nm strikes the metal surface?
