Ruth ford over turned thomsons model in 1911 with his well known gold foil experiment in which he demonstrated that the atom has a tiny heavy nucleus rutherford designed an experiment to use the alpha particles emitted by a radio active element as probes to the unseen world of atomic structure. hey hope this
