Particle

Particles are very often represented as dots. This figure could represent the movement of atoms in a gas, people in crowds or stars in the night sky.

A proton is composed of three quarks.

A particle is a minute fragment or quantity of matter. In the physical sciences, a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume or mass. They vary greatly in size, from subatomic particles like the electron, to microscopic particles like atoms and molecules, to macroscopic particles like powders and other granular materials. Particles can also be used to create scientific models of even larger objects, such as humans moving in a crowd.
