British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.
Who proposed standard symbols for elements?
Dalton 1808 – 36 elements
Dalton’s theory was presented in New System of Chemical Philosophy (1808-1827). Since the old alchemical 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.
