Dalton atommodell experiment
WebJohn Dalton studerade resultaten från dessa och år 1803 presenterade han en samlad atomteori där han bevisade att en kemisk reaktion innebär en omfördelning av atomer. Han bekräftade att massan bevaras under reaktioner och skapade föregångaren till det periodiska systemet som Dmitri Mendeleev visade upp 1869.
