Three Experiments and One Big Idea.
Thomson appreciated in 1897 that the cathode rays are formed from negative electrically charged very small particles. These particles are the electrons. From this Thomson concluded that the atom.
It figured out a bunch of details about electrons and specially that the atom is not the smallest particle in matter. In 1878 William Crooks observed that a beam of light travels from cathode to the anode when he lowered the pressure of the Crooks Tube with a gas to 1Pa. In 1897 J.J. Thomson did experiments to figure out the characteristics of the Cathode Rays. To read more of the experiments.
British scientist JJ Thomson (1856-1940) was awarded a Nobel Prize in Physics for his contributions to modern atomic theory. JJ Thomson and a cathode ray tube Background info: JJ Thomson used a cathode ray tube in his experiments.
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. He is known for the Thomson atomic theory. Many scientists studied the electric discharge of a cathode ray tube.
J J Thomson and the Cathode Ray Tube. From MIT 3.091-Lec 3 Donald Sadoway.. J J Thomson publishes his discovery of a subatomic particle common to all matter. The New Model of the Atom-Thompson knew atoms were neutral, so there must be a balance of negative and positive particles. This new model is referred to as the Plum Pudding Model.
J.J. Thomson Joseph John Thomson was born in Manchester, England in 1856. Thomson was indeed a good scientist, but he did not know that at first. He attended college at a time when science was finally getting recognized as an important subject (Morgan).
The Thomson Cathode Ray Tube experiment was done in the nineteenth century by J. J. Thomson. In the experiment, he had empty glass tubes which he used to shoot rays of electricity. He proposed the idea that in the tubes were not only atoms but even smaller particles within the atoms.
