Definition. A subatomic particle is a unit of matter or energy that's the fundamental makeup of all matter. According in modern atomic theory, an atom has a nucleus, which is its center, or core. The nucleus contains subatomic particles: protons and neutrons. Protons are positively-charged particles. Neutrons are neutral particles. Surrounding the nucleus is a cloud of very small subatomic particles, called electrons. Electrons are negatively-charged particles.
Generally speaking, subatomic particles are particles smaller than an atom. There are the three basic ones that make up atoms, and you probably already know that those are protons, neutrons and electrons.
