The antiparticle of a neutron.
- One can imagine atoms that are made of antiparticles: antiprotons, antineutrons, and positrons.
- Antimatter is matter composed of antiparticles, such as positrons, antineutrons and antiprotons.
- The antineutron, although neutral like the neutron, is distinguishable from the neutron because it is composed of two anti-down quarks and one anti-up quark.
