A '''neutron''' is the neutral particle in an [[atom]]'s [[nucleus]]. It is a [[baryon]], comprised of two down [[quark]]s 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 decay|beta radiation]] is the conversion of a neutron into a [[proton]] which emits an [[electron]] and an [[anti-electron neutrino]].
