WebThe Discovery of the Electron (J. J. Thomson) In 1897, J. J. Thomson found that the cathode rays can be deflected by an electric field, as shown below. By balancing the effect of a magnetic field on a cathode-ray beam with an electric field, Thomson was able to show that cathode "rays"are actually composed of WebHe discovered the electron, cathode ray experiment, and plum pudding model which was later disapproved. "The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively ...
