Early atomic model experiments

Thomson’s discovery of the electron in 1897 and the atomic model, with his findings of the atom containing electrons, each with an individual unit of negative charge. Thomson also found that electrons were very light when compared to the mass of the atoms in which they came from. This is because atoms were known to be electrically neutral, the remainder of the atom had to be positively charged and form most of the weight in the atom. Thomson used his plum pudding model of the atom to present this. How did thomson discover the atom? Thomson discovered the atom through his use of Crookes, or cathode ray, tube in his experiments. He showed that cathode rays were negatively charged, also he looked at positively charged
