WebJ.J. Thomson had discovered the electron in 1897 and had measured its charge-to-mass ratio. The next step was to determine the electron’s charge separately. Thomson and others tried to measure the fundamental electric charge using clouds of charged water droplets by observing how fast they fell under the influence of gravity and an electric field. Web14 dec. 2024 · Sir Joseph John Thomson was a British physicist and Nobel Laureate. He was well-known for the discovery of the electron. In 1897, he showed that cathode rays were composed of very small negatively charged particles. These particles later were named electrons. The apparatus of his experiment is called the cathode-ray tube (CRT).
