neutron
Proton's uncharged neighbor
A neutron is a subatomic particle found in the nucleus of atoms, carrying no electric charge—unlike the positively charged proton or negatively charged electron.
Neutrons help bind the nucleus together; their number determines an element's isotope.
Free neutrons are unstable and decay within minutes.
Neutron stars are collapsed stellar remnants composed almost entirely of neutrons.
