* Neutron: A fundamental particle found in the nucleus of an atom.

* Neutrino: A fundamental particle with very little mass and no charge.

* Photon: A fundamental particle that carries electromagnetic radiation.

* Meson: A composite particle made up of quarks and antiquarks, some of which are neutral.
