cuz they were pagal and they were stupid to do this cuz then we had to study this !
Leukippus, Democritus, Dalton, Bohr, Rutherford, Thomson and many others.
Particles in the atom: Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
the electron was first discovered in 1897 by Joseph john Thomson and the proton was discovered in 1913 by ernest Rutherford
We should never say that an experiment has proven something. The Rutherford gold foil experiment led to the hypothesis that an atom's positive charge is concentrated in an incredibly small space at the atom's center.

The atomic model l
According to Thomson's atomic theory, the mass of an atom was special evenly throughout its volume. Errest Rutherford's experiment proved this wrong.

Both had electrons, different -- rutherford had a nucleus.
It's J.J. Thomson He had the plum pudding experiment The answer is Thomson
Proton discovered by Ernest Rutherford Neutron discovered by James Chadwick Electron discovered by J. J. Thomson
Thomson's watermelon model was further enhanced by Rutherford with his Gold foil experiment. This is also known as atomic model and led to the scientific study of atom's structure.
Joseph John Thomson (1856 - 1940) is credited with discovering the electron. He worked extensively with cathode ray(electrons) tubes and his work led to the development of the mass spectroscope. He developed a model of the atomand, like many brilliant scientists, his model was further refined leading to increasingly better understanding of the structure of the atom. Thomson's student Ernest Rutherford actually proved that Thomson's model of the atom was incorrect.Thomson then went on to study the nature of positively charged ions.Thomson was awarded the Nobel Prize for Physics in 1906.Rutherford was awarded the Nobel Prize for Chemistry 1908 for his work on alpha particles.JJ Thomson's son was also a winner of the Nobel Prize for Physics in 1937.
Example of scientists: Dalton, Thomson. Rutherford, Bohr etc.
That most of an atom's mass was packed in a central nucleus
