Neutron - Wikipedia
WebThe neutron is a subatomic particle, symbol n or n 0, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, they are both referred to as nucleons.
