Rutherford and Soddy's theory stated that uranium successively disintegrated to lead. Rutherford discover the proton. He also discovered that the atom is mostly space.
The Atomic Theory
Rutherford's theory is known as the Rutherford model or Rutherford atomic model. It describes the structure of an atom as a dense positively charged nucleus surrounded by orbiting electrons.
D. E. Rutherford has written: 'Introduction to lattice theory' -- subject(s): Lattice theory
Rutherford.
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.
Ernest Rutherford conducted his studies to test J.J Thompsons 'Plum Pudding' theory.
1955
Ernest Rutherford contributed to the atomic theory through his gold foil experiment. He discovered that there was a positively charged central core to the atom and he called it the nucleus.
The Rutherford-Atomic Theory was published by Ernest Rutherford. It described the atom as having a central positive nucleus surrounded by negative orbiting electrons.
Rutherford discovered and proposed the theory that every atom consists of Nucleus. electrons revolve around the nucleus in circular orbits. His theory is regarded as Nuclear theory of atomic model. He also proposed the theory of neutrons. James chadwick one of his associates proved that and earned nobel prize

The structure of an atom is just like the solar system. ==================================== The above answer is incorrect. Rutherford's atomic theory included the idea that Elcectrons float around a nucleus with protons.
