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.
The atoms are made up of three basic sub-atomic particles. 1  Electron - Negatively charged particle present outside the nucleus of an atom. 2  Proton - Protons are positively charged and are present inside the nucleus.  Neutron - Neutrons are neutrally charged particles, present within the nucleus of an atom.
