This website can answer your question. It basically says that most of an atom's mass is found in it's nucleus. A nucleus contains the protons and the neutrons of an atom. Most of the atom, though, is made up of empty space. This site also describes Ernest Rutherford's gold foil experiment.
Rutherford
Rutherford discovered that the nucleus occupies a very small volume compared to the overall size of the atom. He found that the nucleus is extremely dense and contains nearly all the mass of the atom, while the rest of the atom is mostly empty space.
A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles. Also Rutherford discovered atomic nucleus and the proton.

1909-1911
The discovery of the nucleus by Ernest Rutherford in the early 20th century provided evidence that the majority of an atom's mass is concentrated in a small, dense region at the center. Rutherford's gold foil experiment demonstrated that most of the alpha particles passed through the foil undeflected, indicating the presence of a concentrated mass at the center of the atom. This led to the development of the nuclear model of the atom, which suggests that the nucleus contains the majority of an atom's mass.
Ernest Rutherford is the scientist who proposed that most of the mass of an atom is concentrated in a small, dense, positively charged nucleus, based on his gold foil experiment which led to the discovery of the atomic nucleus.
