WebThe main points of Dalton's atomic theory are: Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass. Compounds are produced through different whole-number combinations of atoms. WebDalton used three laws of chemical reactions as a basis for his theory: (1) The Law of Conservation of Mass, (2) The Law of Definite Proportions, and (3) The Law of Multiple Proportions. Dalton’s atomic theory provides a microscopic explanation of the many macroscopic properties of matter.
