Flexi Says: In 1897, J. J. Thomson discovered the first subatomic particle, the electron, while researching cathode rays.To explain the neutrality of atoms, Thomson proposed a model of the atom in which negative electrons are scattered throughout a sphere of positive charge. He called his atom the plum pudding model.
What did J.J. Thomson discover with the cathode ray tube? Cathode: The cathode is the positive terminal of a battery and the negative terminal of an electrolytic cell.
J.J. Thomson: J.J. Thomson was a brilliant physicist who began his career early when, at the age of 14, he enrolled in Owens College. Later, he would study at Trinity College and become the director of the famed Cavendish Laboratory at the age of 27 years old. His research regarding electrons earned him a Nobel Prize in 1906, just two years ...
May 31, 2024 · Ernest Rutherford (born August 30, 1871, Spring Grove, New Zealand—died October 19, 1937, Cambridge, Cambridgeshire, England) was a New Zealand-born British physicist considered the greatest experimentalist since Michael Faraday (1791–1867). Rutherford was the central figure in the study of radioactivity, and with his concept of the nuclear ...
21. Scientists J. J. Thomson and William Thomson (Lord Kelvin) made numerous contributions to our understanding of the atom's structure. a. Which subatomic particle did J. J. Thomson discover, and what did this lead him to postulate about the nature of the atom? b. William Thomson postulated what became known as the "plum pudding" model of the ...
Joseph John Thomson (J. J. Thomson, 1856-1940; see photo at American Institute of Physics) is widely recognized as the discoverer of the electron. Thomson was the Cavendish professor of Experimental Physics at Cambridge University and director of its Cavendish Laboratory from 1884 until 1919. For much of his career, Thomson worked on various ...
