Joseph Proust's contribution to the atomic theory was when he stated that a substance has the same make up where ever or how ever it was made. He discovered that the same substance found in different areas of the world had the same elements at the same ratio. He called this his Law of Definite Proportions or Proust's law. He is best known for his pioneering work in the development of modern atomic theory, and his research into colour blindness. Approximately fifty years after John Dalton's proposal of the atom, evidence began to accumulate which suggested that the atom might not be the solid sphere that Dalton had envisioned. The contributions to atomic theory of Dalton, Proust, Lavoisier, as well as those of the Arabic scientist, Jābir ibn Ḥayyān, who died in 803 AD, are discussed.

Dalton’s theory provided a framework that was later expanded to demonstrate that the atom is composed of subatomic particles and that atoms of the same element can differ in mass, known as isotopes. He discovered that the same substance found in different areas of the world had the same elements at the same ratio. N.p., n.d. Atomic Theory 1. 2 hours ago by. Atomic theory is the scientific theory that matter is composed of particles called atoms.Atomic theory traces its origins to an ancient philosophical tradition known as atomism.According to this idea, if one were to take a lump of matter and cut it into ever smaller pieces, one would eventually reach a point where the pieces could not be further cut into anything smaller.
