* Protons: Positively charged particles found in the nucleus of an atom.
* Neutrons: Neutrally charged particles found in the nucleus of an atom.
* Electrons: Negatively charged particles that orbit the nucleus of an atom.
However, there are many more subatomic particles that have been discovered through particle physics, including:
* Quarks: Fundamental particles that make up protons and neutrons.
* Leptons: Fundamental particles that include electrons and neutrinos.
* Bosons: Particles that mediate forces, such as photons (light particles) and gluons.
So, depending on how you define "subatomic particles," there are either three or many more!
