Over the years, the exact process by which Dalton devised his corpuscleic supposition has been a topic of much debate. His own recollections are misidentify; similarly, there is little consensus among the reported accounts of friends. There are some(prenominal) potential routes of development, and each has both reasonable documentation and disparities (4:106).
Dalton's "atom" was very similar to the "particle" described by Sir Isaac newton in his Opticks. Newton's influence on Dalton is emphasized by the concomitant that many of his passages were copied into Dalton's notebooks. One such passage described atoms as indivisible homogenous particles. It reads as follows: ". . . god in the solution formed matter in solid, massy, arduous, impenetrable, movable particles . . . so hard as never to wear or break in pieces (4:106-121)." In yet another passage, Newton describes the nature of these particles: "God is able to create particles of matter of some(prenominal) sizes and figures, and in several proportion

In addition to particle size, 1805 also marked the year that Dalton began to study particle weight. Similarly, the investigator began to regard the number of atoms in a shitn volume. This research at last extended beyond gases, to include both liquids and solids (4:138-140).

Eventually, in 1805, Dalton constructed the atomic theory of the constitution of gases (6:30-31). He realized that if particles of dissimilar gases uncomplete repelled nor attracted each other, then each gas must brook certain unique characteristics. Dalton postulated, therefore, that "every species of pure elastic silver-tongued has its particles globular and all of a size; but that no two species agree in the same size of their particles, the compel and temperature being the same (4:106-121)." Moreover, these alike particles could be uniformly form like "piles of shot;" whereas particles of unlike size would give rise to unstable arrangements which would keep the gases mixed (4:106-121)."
