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. WebSir William Crookes invented the Crookes Tube, and used this to observe Cathode Rays. Cathode Rays are streams of electrons which come from the Cathode of a vacuum. Originally, Sir William Crookes believed that the particles he observed in these rays were atoms or molecules, however at further observation he discovered them to be electrodes.
