Rutherford carried out the alpha particle scattering experiment, where positively charged alpha particles were fired at thin gold foil - most went through, but some bounced off. This lead to the nuclear model of the atom, which believes that most of an atom is empty space, except the positively charged nucleus, which is where the mass is concentrated.
