What are all the subatomic particles in existence?

An alternative view: Entire space, outside basic 3D matter-particles, is filled with an all-encompassing universal medium, structured by quanta of matter. Corpuscles of radiation (photons) are the most basic 3D matter-particles. Each photon has a ... read more

Various extensions of the Standard Model predict the existence of an elementary graviton particle and many other elementary particles. Composite subatomic particles (such as protons or atomic nuclei) are bound states of two or more elementary particles. read more

Subatomic particle, also called elementary particle, any of various self-contained units of matter or energy that are the fundamental constituents of all matter. Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons. read more
