Particle - Wikipedia
WEBIn the physical sciences, a particle (or corpuscule in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or mass.

WEBNov 12, 2020 · What Is a Particle? It has been thought of as many things: a pointlike object, an excitation of a field, a speck of pure math that has cut into reality. But never has physicists’ conception of a particle changed more than it is changing now. Elementary particles are the basic stuff of the universe. They are also deeply strange.

WEBOct 22, 2020 · The strong force binds quarks of different colors together into composite particles such as protons and neutrons, which are “colorless,” with no net color charge. Quarks transform from one color to another by absorbing or emitting particles called gluons, the carriers of the strong force. These interactions form the sides of a triangle.

WEBThe theory describes two fundamental types of particles: fermions, which makes up all of the ‘stuff’ around us, and bosons, which mediate how fermions interact with one another. Two familiar examples are the electron (a fermion) and a photon (a boson), the particle of light which carries the electromagnetic force.

WEBClassifications of Elementary Particles. A large number of subatomic particles exist in nature. These particles can be classified in two ways: the property of spin and participation in the four fundamental forces. Recall that the spin of a particle is analogous to the rotation of a macroscopic object about its own axis.
Elementary particle - Wikipedia
WEBIn particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons.
