The Feynmann diagram of the neutron beta decay process
A neutron is the neutral particle in an atom's nucleus. It is a baryon, comprised of two down quarks and an up quark It keeps the positive protons in the nucleus from being pushed apart from each other by their like charges. A lack or excess of neutrons causes an atom to become unstable; beta radiation is the conversion of a neutron into a proton which emits an electron and an anti-neutrino.
See nucleon.
