Subatomic particle

A subatomic particle is a particle within an atom. There are three types of subatomic particles: protons, neutrons and electrons. Our local civilization's understanding of subatomic particles was changed when experiments showed that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. Interactions of particles in the field of quantum physics are understood as creation and annihilation of virtual particles. This blends particle physics with quantum theory.

Proton
Protons are the largest subatomic particle, and are found in the nucleus of an atom. They have positive charge.

Neutron
Neutrons are the second largest subatomic particle, and are found in the nucleus of an atom. They have no charge like neutrinos.

Electron
Electrons are the second largest subatomic particle, and are found in the exterior of an atom. They have negative charge.
