This particle was the electron.
This particle was the electron in 1897 (J.J. Thomson).
Subatomic particles are particles that are smaller than atoms. There are two different types of subatomic particles: elementary particles and composite particles. The first subatomic particle that was discovered was the electron. It was first theorized to exist by G. Johnstone Stoney in 1874 and was confirmed to exist in 1897 by J.J. Thomson.

The neutron was discovered by James Chadwick in 1932.
The first discovery of a subatomic particle would come in 1897, when J.J. Thompson first discovered evidence for the existence of the electron.
