John Dalton was an English chemist. His ideas form the atomic theory of matter. Here are his ideas. • All elements are composed (made up) of atoms. It is impossible to divide or destroy an atom. • All atoms of the same elements are alike. (One atom of oxygen is like another atom of oxygen.) • Atoms of different elements are different.
Dalton's theory quickly became the theoretical foundation in chemistry. All matter is made of atoms. Atoms are indivisible and indestructible. Compounds are formed by a combination of two or more different kinds of atoms. A chemical reaction is a rearrangement of atoms.
