Actually there are many subatomic particles from them following were discovered by:
1)Electron discovered by J.J Thomson through discharge tube experiment.
2)Proton was discovered by Ernest Rutherford through discharge tube experiment.
3)Neutron was discovered by James Chadwick by Artificial radioactivity.
If you think to particles in the atom: the neutron was discovered in 1932 by James Chadwick.

Binomial particles like protons, neutrons, and electrons were discovered by multiple scientists. The electron was discovered by J.J. Thomson in 1897, the proton was discovered by Ernest Rutherford in 1919, and the neutron was discovered by James Chadwick in 1932.
Three subatomic particles were discovered in the 1900s: the neutron in 1932, the positron in 1932, and the neutrino in 1956.
The neutron was discovered in 1932 by James Chadwick.
The zigzag motion of particles was discovered by Japanese physicist Shoji Asada in 1952. This phenomenon is known as Brownian motion and is caused by the random movement of particles suspended in a fluid.
The proton was discovered by Ernest Rutherford in 1917-1919.
The random movement of particles, known as Brownian motion, was discovered by the Scottish botanist Robert Brown in 1827 while observing the movement of pollen grains suspended in water under a microscope.

Michael Faraday discovered this in 1831.
The three types of radioactivity discovered by Rutherford are alpha particles, beta particles, and gamma rays. Alpha particles are positively charged, beta particles are electrons or positrons, and gamma rays are high-energy electromagnetic radiation.
