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.
