A quark (/ˈkwɔːrk, ˈkwɑːrk/ ⓘ) is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks, and electrons. Owing to a phenomenon…
