Cathode rays were discovered by Johann Wilhelm Ritter in 1802. Ritter observed that when he placed a metal plate between a negatively charged cathode and an anode in a glass tube, the intensity of the light emitted by the tube decreased. Ritter concluded that the cathode rays were negatively charged and were being repelled by the metal plate.<\/li>\n<li>Thomson\u2019s experiment consisted of a glass tube with a cathode and an anode, and a metal plate between the cathode and anode. Thomson used a magnet to deflect the cathode rays. When the magnet was placed near the cathode, the cathode rays were deflected towards the anode. When the magnet was placed near the anode, the cathode rays were deflected away from the anode. Thomson concluded that the cathode rays were negatively charged and were being repelled by the metal plate. Thomson also concluded that the cathode rays were made up of negatively charged particles that he called electrons.<\/li>\n<\/ul>\n<p>For more visit <a href=\"https:\/\/infinitylearn.com\/surge\/chemistry\/electrons\/\">Electrons &amp;#8211; Definition, Properties, Thomson\u2019s Cathode Ray Experiment<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>An Introduction to Electrons Electrons &#8211; Definition: An electron is a negatively charged subatomic particle that is found in the [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_yoast_wpseo_focuskw":"Electrons -
