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.

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.

What subatomic particle did the gold foil experiment discover?
Rutherford's gold foil experiment did not discover the existence of any subatomic particles, but it did show the existence of a small, tightly packed, positively charged nucleus and thus led to the discovery of protons.
