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.
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.
For the particles in the atom:
Neutron: James Chadwick, 1932
Electron: J. J. Thomson, 1897 Proton: Ernest Rutherford, 1919

What charge does the subatomic particle that Thompson discover have?
negative charge
What does it mean when a subatomic particle is in the atom?
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.
