WebJohn Dalton (1766 - 1844 C.E.) 1803 C.E. - 1884 C.E. John Dalton believed in Democritus' work. His theory consisted of four basic ideas: 1) All matter is composed of atoms that are indivisible. 2) All atoms are identical in properties, such as size and mass. 3) Atoms are rearranged as a chemical reaction occurs. WebEventually, his cathode ray particles were given a more familiar name: electrons. The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms were indivisible.
