Did other scientists believe John Dalton?

Yes, many scientists supported John Dalton's atomic theory, which proposed that matter is composed of indivisible atoms and that each element has unique atoms with specific weights. His work laid the foundation for modern chemistry and was influential in the scientific community. However, some aspects of his theory faced skepticism and refinement as new discoveries emerged, particularly regarding atomic structure and the existence of subatomic particles. Overall, Dalton's contributions were pivotal in advancing the understanding of chemical reactions and the nature of matter.
