ITermove an electron from the surface of the solid element. The Work function for lithium is 279.7 kJ/mol (that 1s, 1 takes 279.7 kKJ of energy to remove one mole of electrons from one mole of Li atoms on the surface ofLi metal). What is the max- lmum wavelength oflight that can remove an electron from an atormn on ffhe surface of lithium metal? It takes 208.4 kJ of energy to remove lmole ofelectrons from an atom on 負e surface of rubidium metal. How much energy does it tfake to remove a single electron from an atom on the surface of solid rubidium? What is the maximum wavelength 說人計生 加計
