By using photons of specific wavelengths, chemists can dissociate gaseous hi to produce h atoms with certain speeds. when he dissociates, the h atoms move away rapidly, whereas the heavier i atoms move more slowly. (a) if a photon of 245 nm is used, what is the excess energy (in j) over that needed for dissociation
