J. j. thomson's experiments supported the existence of a particle that deflected away from a negative charge and toward a positive charge. ernest rutherford found that when positive particles were fired at gold foil, some of the particles deflected rather than passing straight through. taken together, these experiments support our understanding of the a. flavors or quarks b. structures of the atom c. specific gravity of gold d. law of conservation of energy
