Dalton's idea of matter is known as John Dalton's atomic theory. Dalton first proposed his atomic theory in 1803. Matter is composed of very tiny indivisible particles called atoms. Atoms are incapable of being destroyed or created.
English chemist and physicist John Dalton extended Proustâs work and converted the atomic philosophy of the Greeks into a scientific theory between 1803 and 1808. His book A New System of Chemical Philosophy (Part I, 1808; Part II, 1810) was the first application of atomic theory to chemistry.
