This scientist led a series of experiments that used high speed lightweight atoms called alpha particles to bombard very thin pieces of gold foil. Some of the alpha particles went straight through the foil, but a few alpha particles bounced back. The scientist used this information to hypothesize that an atom is made of a tiny dense nucleus surrounded by a region of mostly empty space.
