Thomson discovery of electron
WebJ.J. Thomson discovered the electron. Atoms are neutral overall, so in Thomson’s ‘plum pudding model’: atoms are spheres of positive charge; electrons are dotted around inside; WebIn 1897 JJ Thomson discovered the electron by using cathode-ray tubes. Three big experiments that helped shape the electron and the atom concept that we have today are the discovery of the electron and the plum pudding model, Rutherford's gold foil experiment, and the Millikan oil-drop experiment. The gold foil experiment is one of the most ...
