The work function of an element is the energy required to remove an electron from the surface of the solid. the work function for rhodium is 480.5 kj/mol (that is, it takes 480.5 kj of energy to remove 1 mole of electrons from 1 mole of rh atoms on the surface of rh metal). what is the maximum wavelength of light that can remove an electron from an atom in rhodium metal?
