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.
the makeup of atoms in terms of the existence of three types of subatomic particles: protons, neutrons, and. This model of the atom is actually an oversimplification. nuclear physicists -picture of the atom has lost. its simplicity -Experimental evidence indicates that protons and neutrons. themselves are made up of even smaller particles.
