Neutron - Wikipedia
网页The neutron is a subatomic particle, symbol n or n 0, which has no electric 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.
