... The atomic theory was presented by the British chemist John Dalton (1766-1844) in the early 1800s. It is one of the greatest advances in the history of chemistry. “Whether matter be atomic or not, this much is certain, that granting it to be atomic, it would appear as it now does.”(by Micheal Farada ...
