In chemistry and physics, atomic theory is a scientific theory of the nature of matter, which states that matter is composed of discrete units called atomsit began as a philosophical concept in ancient greece and entered the scientific mainstream in the early 19th century when discoveries in the field of chemistry showed that matter did indeed behave as if it were made up of atoms.
