In the physical sciences, a particle (or corpuscle in older texts) is a small localized object which can be described by several physical or chemical properties, such as volume, density, or …

This is a list of known and hypothesized microscopic particles in particle physics, condensed matter physics and cosmology. Elementary particles are particles with no measurable internal …

In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. [1] The Standard Model presently recognizes seventeen …

In a solid, the particles pack together tightly in a neat and ordered arrangement. The particles are held together too strongly to allow much movement but the particles do vibrate.
