In the physical sciences, a particle is a small localized object to which can be ascribed several physical or chemical properties such as volume, density or mass.

An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.

A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

A particular kind of matter with uniform properties is called a substance.
