Question

Why did the better part of a century pass between Thomson’s work and Dalton’s work? Was no one interested in researching the atomic theory?

Answer 1

During the time of Thompson and Dalton, no one studied their theories because the technology at the time didn't allow for further study in conducting their works. People were focused on other things. But it was revived and revised because of Neils Bohr and his atomic structure that led to more theories and eventually studies that continued on the works of Thompson and Dalton.
