j. j. thomson's experiments with cathode ray tubes showed that all atoms ... Thomson's plum pudding model of the atom had negatively-charged ... Based on these results, Rutherford proposed the nuclear model of the atom ... The discovery of the electron disproved the part of Dalton's atomic theory that assumed atoms.
