neutron
The neutron was discovered in 1932 by James Chadwick.
Quark is the smallest particle ever discovered.
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.
Basically, atoms are made up of subatomic particles. Subatomic, sub- meaning smaller that, so subatomic particles means "a particle smaller than an atom". So It means that it is a particle within the atom.

You think probable to neutron - James Chadwick, 1932.
This particle was the electron.
The concept of subatomic particles emerged in the late 19th and early 20th centuries through the research of scientists such as J.J. Thomson, Ernest Rutherford, and Niels Bohr. The discovery of specific subatomic particles like the electron, proton, and neutron can be attributed to a combination of experimental observations and theoretical advancements by multiple scientists over time.
The smallest particle of matter is an atom, which was discovered in the early 20th century through experiments such as the gold foil experiment by Ernest Rutherford. It was found that atoms are made up of even smaller particles called protons, neutrons, and electrons.
