He simply proposed that the 'indivisible' parts of masses, known as atoms, were tiny spheres. He did no experiments to test this, but future physicists would begin to show interest in this theory and begin to evolve it further. Now, our current theory is that atoms are composed of a nucleus(where there are protons and neutrons), and energy shells(where electrons orbit the nucleus at incredibly high speeds).
john dalton developed the atomic theory , which he published in 1803
John Dalton first pursued research into atomic theory. He was the first person to propose the existence of the atomic structure.
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
In my textbook it sayes that actually Dalton believed that all substances are made of atoms, and this was part of his atomic theory, which he published in 1803.
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
