The British scientist Ernest Rutherford postulated the nuclear model of the atom in the early 1900s. He described his model as the atom being mostly empty space with electrons having a fixed orbit around the positively charged nucleus of the atom. The experiment he conducted to arrive at the model is known as the thin-foil experiment. He passed a narrow beam of particles through a thin film of metal foil and observed that the particles were only slightly scattered. It was with this observation that he concluded that most of the mass of a particle is concentrated only in a minute fraction of the total volume of the atom.
