Dalton was an English chemist and teacher who used experimental evidence to form the atomic theory of matter: 1  All elements are composed (made up) of atoms. 2  All atoms of the same element are alike. 3  Atoms of different elements are different. 4  Atoms of different elements combine to form a compound. These atoms have to be in definite whole number ratios. For example, water is a compound made up of 2 atoms of hydrogen and one atom of oxygen. (A ratio of 2:1) Three atoms of hydrogen and 2 atoms of oxygen cannot combine to make water. Chemical reactions occur when atoms are separated, joined, or rearranged.
