Democritus was not able to describe atomic model in detail. Some basic weakness of this theory include: 1. Weakness of Democritus theory of Atoms. Dalton published the first table of relative atomic weights of … Later, in 1808, Dalton published his famous diagram of combined "atoms": On his theory, Democritus only stated that atoms are in the solid form in the void sphare. Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. His law on partial pressure became known as Dalton's Law. John Dalton wrote a series of papers describing gas laws. Thomson Atomic Model. Joseph John Thomson was born in Cheethan Hill, England and was a professor of experimental physics at the Carendish Laboratory, Cambridge, London. 3. Similar to these views, in 1803 John Dalton took the atomic weight of hydrogen, the lightest element, as unity, and determined, for example, that the ratio for nitrous anhydride was 2 to 3 which gives the formula N 2 O 3.Dalton incorrectly imagined that atoms "hooked" together to form molecules. In 1897, there was a scientist named J.J. Thomson who did a research to refine Dalton’s atomic theory. Although his theory about discolored liquid did not pan out, color blindness became known as Daltonism. As the first atomic theory in the world, Democritus theory of atoms should have many flaws.
