John Dalton. While it must be assumed that many more scientists, philosophers, and others studied the composition of matter after Democritus, a major leap forward in our understanding of the composition of matter took place in the 1800s with the work of the British scientist John Dalton. He started teaching school at age twelve, and was ...
Engraving of John Dalton by William Henry Worthington after a painting by William Allen, 1823. Science History Institute. In explaining the law of partial pressures to skeptical chemists of the day—including Humphry Davy —Dalton claimed that the forces of repulsion thought to cause pressure acted only between atoms of the same kind and that ...

John Dalton and the development of the atomic theory. By far Dalton’s most influential work in chemistry was his atomic theory. Attempts to trace precisely how Dalton developed this theory have proved futile; even Dalton’s own recollections on the subject are incomplete. He based his theory of partial pressures on the idea that only like ...

John Dalton, koji je za mjernu jedinicu uzeo vodikov atom kao najlakši od svih atoma i pridijelio mu vrijednost 1 (poslije je kao jedinica služila i 1/16 mase atoma kisikova izotopa 16 O). Takvo je izražavanje uvedeno iz praktičnih razloga, jer su mase atoma izvanredno malene (na primjer masa je vodikova atoma 1,673 · 10 −27 kg ).
