Answer 1

Dalton 1808 - 36 elements John Dalton (1766-1844) was an English meteorologist who switched to chemistry when he saw the applications for chemistry of his ideas about the atmosphere. He proposed the Atomic Theory in 1803 which stated that
all matter was composed of small indivisible particles termed atoms,
atoms of a given element possess unique characteristics and weight, and
three types of atoms exist: simple (elements), compound (simple molecules), and complex (complex molecules).Dalton's theory was presented in New System of Chemical Philosophy (1808-1827). Since the old achemical symbols were not fit to use in his theory, he proposed a new set of standard symbols for the chemical elements in the first volume of his New System.
