  1. Subatomic particle

    In physical sciences, a subatomic particle is a particle that composes an atom. According to the Standard Model of particle physics, a subatomic particle can be either a composite particle, which is composed of other particles (for example, a proton, neutron, or meson), or an elementary particle, which is not composed of other particles (for example, an electron, photon, or muon). Particle physics and nuclear physics study these particles and how they interact.Experiments show that light could behave like a stream of particles (called photons) as well as exhibiting wave-like properties. This led to the concept of wave–particle duality to reflect that quantum-scale particles behave like both particles and waves; they are sometimes called wavicles to reflect this.Another concept, the uncertainty principle, states that some of their properties taken together, such as their simultaneous position and momentum, cannot be measured exactly. The wave–particle duality has been shown to apply not only to photons but to more massive particles as well.Interactions of particles in the framework of quantum field theory are understood as creation and annihilation of quanta of corresponding fundamental interactions. This blends particle physics with field theory. Even among particle physicists, the exact definition of a particle has diverse descriptions. These professional attempts at the definition of a particle include: A particle is a collapsed wave function A particle is a quantum excitation of a field A particle is an irreducible representation of the Poincaré group A particle is an observed thing


  1. subatomic particle

    A subatomic particle is a particle smaller than an atom, the basic unit of a chemical element. They include particles such as protons, neutrons, and electrons as well as other more exotic particles like quarks, neutrinos, and bosons that make up atoms and carry forces between them. The study of subatomic particles falls under the domain of quantum mechanics and particle physics.


  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.
