  1. Subatomic particle

    In physics or chemistry, subatomic particles are the particles smaller than an atom. There are two types of subatomic particles: elementary particles, which are not made of other particles, and composite particles. Particle physics and nuclear physics study these particles and how they interact. The elementary particles of the Standard Model include: ⁕Six "flavors" of quarks: up, down, bottom, top, strange, and charm; ⁕Six types of leptons: electron, electron neutrino, muon, muon neutrino, tau, tau neutrino; ⁕Twelve gauge bosons: the photon of electromagnetism, the three W and Z bosons of the weak force, and the eight gluons of the strong force; ⁕The Higgs boson. Various extensions of the Standard Model predict the existence of an elementary graviton particle and many other elementary particles. Composite subatomic particles are bound states of two or more elementary particles. For example, a proton is made of two up quarks and one down quark, while the atomic nucleus of helium-4 is composed of two protons and two neutrons. Composite particles include all hadrons, a group composed of baryons and mesons.
