1. Elementary particle

   In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. Particles currently thought to be elementary include electrons, the fundamental fermions (quarks, leptons, antiquarks, and antileptons, which generally are matter particles and antimatter particles), as well as the fundamental bosons (gauge bosons and the Higgs boson), which generally are force particles that mediate interactions among fermions. A particle containing two or more elementary particles is a composite particle. Ordinary matter is composed of atoms, once presumed to be elementary particles – atomos meaning "unable to be cut" in Greek – although the atom's existence remained controversial until about 1905, as some leading physicists regarded molecules as mathematical illusions, and matter as ultimately composed of energy. Subatomic constituents of the atom were first identified in the early 1930s; the electron and the proton, along with the photon, the particle of electromagnetic radiation. At that time, the recent advent of quantum mechanics was radically altering the conception of particles, as a single particle could seemingly span a field as would a wave, a paradox still eluding satisfactory explanation.Via quantum theory, protons and neutrons were found to contain quarks – up quarks and down quarks – now considered elementary particles. And within a molecule, the electron's three degrees of freedom (charge, spin, orbital) can separate via the wavefunction into three quasiparticles (holon, spinon, and orbiton). Yet a free electron – one that is not orbiting an atomic nucleus and hence lacks orbital motion – appears unsplittable and remains regarded as an elementary particle.Around 1980, an elementary particle's status as indeed elementary – an ultimate constituent of substance – was mostly discarded for a more practical outlook, embodied in particle physics' Standard Model, what's known as science's most experimentally successful theory. Many elaborations upon and theories beyond the Standard Model, including supersymmetry, double the number of elementary particles by hypothesizing that each known particle associates with a "shadow" partner far more massive, although all such superpartners remain undiscovered. Meanwhile, an elementary boson mediating gravitation – the graviton – remains hypothetical. Also, according to some hypotheses, spacetime is quantized, so within these hypotheses there probably exist "atoms" of space and time themselves.

1. elementary particle

   An elementary particle is a subatomic particle that is not composed of other particles and is considered a fundamental building block of matter. These particles have no discernable structure and cannot be divided or broken down into smaller particles. Examples include electrons, quarks, neutrinos, and particles associated with force fields such as photons and gluons. Some properties of elementary particles, such as mass, charge, and spin, are quantized in nature. The theoretical understanding and study of these particles falls under the domain of particle physics.

1. Elementary particle

   In particle physics, an elementary particle or fundamental particle is a particle not known to have any substructure, thus it is not known to be made up of smaller particles. If an elementary particle truly has no substructure, then it is one of the basic building blocks of the universe from which all other particles are made. In the Standard Model of particle physics, the elementary particles include the fundamental fermions, and the fundamental bosons. Although elementary particles are not made up of smaller particles, some of them may change to lighter particles. Historically, atoms were once regarded as elementary particles. The word "atom" means "that which cannot be cut" from the Greek word atomos. Later, hadrons such as protons and neutrons were considered elementary. A central feature in elementary particle theory is the early 20th century idea of "quanta", which revolutionized the understanding of electromagnetic radiation and brought about quantum mechanics. For mathematical purposes, elementary particles are normally treated as point particles, although some particle theories, such as string theory, posit that elementary particles have a finite nonzero size.
