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 WebThis video is an explanation of J. J. Thomson's cathode ray tube experiment--an experiment in which the electron was discovered, along with its charge-to-mas...

Thomson won a Nobel Prize in physics for his discovery of the electron. This was the first time a particle smaller than the atom was ever discovered. It led to a new understanding of the atom and a series of different models for the structure of the atom as each new subatomic particle was discovered.

WebHow did JJ Thomson disprove Dalton? In short, Thomson had discovered the existence of particles smaller than atoms. This disproved Dalton's claim that atoms are the smallest particles of matter. From his discovery, Thomson also inferred that electrons are fundamental particles within atoms. reached goal gifWebThomson's measurement convinced him that cathode rays were particles, which were later identified as electrons, and he is generally credited with their discovery. The CODATA recommended value is − e / me = −1.758 820 010 76(53) × 1011 C⋅kg−1.
