J.J. Thomson, chemist, discovered the negative particle (electron) in the atom.
Goldstein, scientist, discovered the positively charged particle (electron) in the atom.
James Chadwick discovered the neutral particle (neutron) in the atom.
Each included the particles that were known at a particular time in their atomic models, but scientist Neil Bohr proposed a perfect atomic model consisting of all these particles, and suggested the electronic configuration.

No one person invented or developed the theory of paleomagnetism. Several different scientists contributed to the development of the theory of paleomagnetism.
Instead of just stating his own personal opinions John Dalton cited evidence to support his atomic theory. The giving of evidence - which could be proved or disproved by others - was what soon resulted in his theory being accepted by scientists.
Benjamin Franklin's contribution to the atomic theory was his proposal that electricity was a fundamental force that could be understood through atomic models. He conducted experiments with electricity and proposed the idea of positive and negative charges, which later contributed to the development of the atomic theory.
Scientists did not reject atomic theory upon discovering that atoms are composed of smaller particles because atomic theory had already provided a robust framework for understanding matter and its properties. The discovery of subatomic particles, such as electrons, protons, and neutrons, actually refined and expanded atomic theory rather than negating it. These discoveries revealed that atoms are not indivisible but are structured entities, leading to a more nuanced understanding of chemical behavior and interactions at the atomic level. This evolution of atomic theory has continued to enhance our comprehension of the physical world.
Scientists had made observations that did not fit exactly with Dalton's theory. Scientists changed the atomic theory to include this new knowledge. While the modern atomic theory is based on Dalton's theory, it is also very different.
there were many scientists that contributed towards it but Joseph j. Thomson, Hans geiger, ernest marsden. ernest Rutherford, Henry moseley and James chadwick all made key discoveries and are the main scientists behind the theory.Alfred Nobel,Mendeleev and Neil Bhorbecause theire are the great scientistChadwick explain the atomic theoryniels hendrik bohrmitchell creech
