An atom is building block of matter. The atom is further divided into subatomic particles, i.e., electrons, protons, and neutrons. Here, neutrons and protons are present in nucleus of an atom, thus called neucleons.

Electron was discovered by Joseph John Thomson (J.J. Thomson) in 1897 by cathode ray experiment.

Proton was discovered by Ernest Rutherford in 1909 using the famous gold foil experiment.

James Chadwick discovered neutron in 1932.
