The work function of an element is the energy required to remove an electron from the surface of the solid. The work function for lithium is 279.7 kJ/ mol (that is, it takes 279.7 kJ of energy to remove 1 mole of electrons from 1 mole of Li atoms on the surface of Li metal). What is the maximum wavelength of light that can re-move an electron from an atom in lithium metal?
