What name is given to the elementary particle that carries the electromagnetic force?
Force carrier Force carrier In particle physics, force carriers or messenger particles or intermediate particles are particles that give rise to forces between other particles. These particles are bundles of energy (quanta) of a particular kind of field. There is one kind of field for every type of elementary particle. For instance, there is an electric field whose quanta are electrons, and an electromagnetic field whose quanta are photons. The force carrier particles that mediate the electromagnetic, weak, and strong interactions are called gauge bosons. In particle physics, quantum field theories such as the Standard Model describe nature in terms of fields.
Elementary particle Elementary particle In particle physics, an elementary particle or fundamental particle is a with no substructure, thus not composed of other particles. Particles currently thought to be elementary include 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". Everyday matter is composed of atoms, once presumed to be matter's elementary particles—"atom" meaning "unable to cut" in Greek—although the atom's
