He discovered the electron which has a negative charge of 1.602 x 10-19 coulombs and a mass of 9.1 x 10-31 kg.
Neutron: James Chadwick, 1932 Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919
There are 3 subatomic particles in an atom, electrons, protons, and neutrons. The first discovered was the electrons by J.J. Thomson in 1897. The second discovered was the protons by Ernest Rutherford in 1919. The third discovered was the neutrons by James Chadwick in 1932.

False Einstein was looking at a glass of water on a table and noticed there was pollen on the surface and it was moving the table was not moving the glass was not moving so he came to the conclusion that the water itself was moving thus the discovery of the atom.
Walter Baade and Fritz Zwicky proposed the existence of the neutron star in 1934. Antony Hewish and Samuel Okoye discovered "an unusual source of high radio brightness temperature in the Crab Nebula" in 1965, which turned out to be the Crab Nebula neutron star.
This particle was the electron in 1897 (J.J. Thomson).
It was J. J. Thomson (Joseph John Thomson)
