The neutron is a subatomic particle, symbol n or n0 , with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons constitute the nuclei of atoms.
Atoms are made up of even smaller particles called electrons, protons, and neutrons. Each of these particles has a different electrical charge. Protons are positively charged, neutrons have no charge, and electrons are negatively charged. The protons and neutrons of an atom reside in a central body called a nucleus.
