Particle

particle[edit | edit source]

An aggregation of sufficiently many atoms or molecules that it can be assigned macroscopic properties such as volume, density, pressure, and temperature.

But sometimes by particle, without qualification, is meant a subatomic particle such as the proton or neutron (which themselves are composed of other "elementary particles") or the electron.
See also particles.
