Webb14 apr. 2024 · John Dalton (1766-1844) is the founding father of atomic theory, and his theory the “first scientific theory of atoms” based on empirical evidence. While the concepts he used in creating his theory were actually based on the work of other scientists, he combined them into a theory that was measurable and testable. WebbRUTHERFORD’S EXPERIMENT CENTRAL NUCLEUS The earlier “plum pudding” theory of atomic structure was shattered and a new theory of central nucleus was put forward. The atom’s mass is not uniformly distributed. Rutherford hypothesized that most of the mass and all of its positive charge are centered in a very small region called nucleus.
