Did J.J. Thomson Discover the Electron? - IEEE Spectrum

WebDiscovery of the electron - key takeaways. In 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. WebHe postulated that the angular momentum of the electron is quantized—i.e., it can have only discrete values.

WebAccording to the Thomson atomic model, often referred to as the “plum-pudding” model, the atom is a sphere of uniformly distributed positive charge about one angstrom in diameter. Electrons are embedded in a regular pattern, like raisins in a plum pudding, to neutralize the positive charge. WebThomson’s discovery established the particulate nature of electricity. Accordingly, he called his particles electrons. From the magnitude of the electrical and magnetic deflections, …

Web2 de fev. de 2024 · J.J. Thomson is credited with the discovery of the electron, the negatively charged particle in the atom. He is known for the Thomson atomic theory. Many scientists studied the electric discharge of a cathode ray tube. It was Thomson's interpretation that was important. WebThomson knew that atoms had an overall neutral charge. Therefore, he reasoned that there must be a source of positive charge within the atom to counterbalance the negative charge on the electrons. This led Thomson to propose that atoms could be described as …
