Dalton's atomic theory summary

WebSummary. Dalton proposed his atomic theory in 1804. All matter is composed of extremely small particles called atoms. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties. Atoms cannot be subdivided, created, or destroyed. WebMass of electron = 1.602 × 10 −19 C × 1 kg 1.759 × 10 11 C = 9.107 × 10 −31 kg. Scientists had now established that the atom was not indivisible as Dalton had believed, and due to the work of Thomson, Millikan, and others, the charge and mass of the negative, subatomic particles—the electrons—were known.
