John Dalton’s “Aha” Moment: the Origin of the Chemical Atomic Theory

  title={John Dalton’s “Aha” Moment: the Origin of the Chemical Atomic Theory},
  author={Mark I. Grossman},
  pages={49 - 71}
In his only known historical sketch addressing the origin of the chemical atomic theory, John Dalton stated that different atoms have different sizes, a conclusion which led him to an investigation of combining number of atoms and relative weights. Although he stated the idea occurred to him in 1805, his laboratory notes show he developed the first table of atomic weights in 1803. Historians over the years have provided conflicting narratives to explain the different dates. In this paper, I… Expand
