Who disagrees with daltons major points of the atomic theory?

One of the main figures who disagreed with John Dalton's atomic theory was J.J. Thomson, who discovered the electron and proposed the "plum pudding" model of the atom, suggesting that atoms are composed of smaller particles and are not indivisible as Dalton proposed. Additionally, later developments in quantum mechanics and the discovery of subatomic particles contradicted Dalton's idea of atoms as solid, indivisible units. These advancements highlighted the complexity of atomic structure, leading to a more nuanced understanding of matter.
