Dalton's atomic theory principles
WebJun 19, 2024 · The work of Lavoisier and the atomists was furthered in the 18th Century by the British scientist John Dalton. Dalton used the work of Lavoisier and Joseph Proust to examine the ratios of elements that combine to form compounds and look at their ratio of masses. He looked at tin oxide and the combination of masses of oxygen with tin. WebIt was Dalton's analysis of the ratio of oxygen to hydrogen, 8:1 that enabled the identification of hydrogen having an atomic number of 1 and oxygen's atomic number of 8. Total mass is the sum of ...
