WebMoseley, 22, arrived in Manchester in the fall of 1910, just as Rutherford was beginning a series of groundbreaking discoveries about the structure of the atom. Thirteen years earlier, Rutherford’s Cambridge University mentor, J.J. Thomson, had discovered the electron, a tiny, negatively charged particle that he believed was a piece of every ... WebHe then continued his research and developed the first part of the atomic theory. He stated that: 1.

Atoms of different elements can combine to form compound elements.
