WebDalton's atomic hypothesis was a scientific theory on the nature of matter proposed in 1808 by the English physicist and chemist John Dalton. It stated that all matter was composed of microscopic, indivisible components known as atoms. In 1904 Thomson created what became known as the "plum pudding" model. WebCrookes's Cathode: Because a shadow appeared on the positive electrode, Crookes concluded that something (either light or small particles) was traveling from the negative to the positive electrode. Rutherford's Nucleus: He proposed the existence of a massive positive nucleus at the center of each atom that repelled positively charged alpha ...
