WEBDalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties. Dalton based his theory on the law of conservation of mass and the law of constant composition. The first part of his theory states that all matter is made of atoms, which are indivisible.

WEBDalton proposed his atomic theory in 1804. The general tenets of this theory are: All matter is composed of extremely small particles called atoms; Atoms cannot be subdivided, created, or destroyed. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
