The early philisophers (Leukippus and Democritus) 2500 years ago couldnt prove that atoms existed, and people had not discovered the study of matter yet. The idea of Greeks was genial but is only a philosophical suppostion, only that.Dalton combined the idea of elements with the earlier history of the atom, and the chemical and physical knowledge from 1800.
John dalton and Democritus used them
They both thought the same theory but Dalton had evidence to prove it, unlike Democritus.
John Dalton. N.B.: John Dalton [born: September 6, 1776; died: July 27, 1844, at age 67] was an English chemist and physicist who claimed matter was made up of tiny particles and that these particles were identical for any given kind of matter. Moreover, he claimed these particles were indivisible and could neither be created nor destroyed in any chemical process, only be altered in the manner they were grouped.
