The work function of an element is the energy required to remove an electron from the surface of the solid element. 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; l mol Li = 6.022 × 1023 atoms Li). What is the maximum wavelength of light that can remove an electron from an atom on the surface of lithium metal?
