Calculate the energy required to remove 1 electron:
E = 3.461×10‒19 J/electron
3.461×10‒19 J of energy is required to remove a single electron from an atom on the surface of solid rubidium.
It takes 208.4 kJ of energy to remove 1 mole of electrons from an atom on the surface of rubidium metal. (1 mol electrons = 6.022 x 1023 electrons.) How much energy does it take to remove a single electron from an atom on the surface of solid rubidium? What is the maximum wavelength of light capable of doing this?
