When is electron discovered

Electron was discovered by J. Thomson constructed a glass tube which was partially evacuated i. Then he applied a high electrical voltage between two electrodes at either end of the tube. He detected that a stream of particle ray was coming out from the negatively charged electrode cathode to positively charged electrode anode.

This ray is called cathode ray and the whole construction is called cathode ray tube. Sign up. Publications Pages Publications Pages. Recently viewed 0 Save Search. Users without a subscription are not able to see the full content.

Thomson was a physics professor at Cambridge University in the UK. He placed cathode tubes in electric and magnetic fields. He knew that these fields will move particles from side to side, but don't have much effect on how a wave moves. In his experiments, the cathode rays bent over to one side, so Thomson knew the cathode rays must be made of some small particle, which he dubbed a "corpuscle.

Physicists also discovered that electrons were only the most common members of an entire family of fundamental particles, which are still the subject of intensive research to better understand their properties.

Thomson's work earned him recognition as the "father of the electron," and spawned critical experimental and theoretical research by many other scientists in the United Kingdom, Germany, France and elsewhere, opening a new perspective of the view from inside the atom. The knowledge gained about the electron and its properties has made many key modern technologies possible, including most of our society's computation, communications, and entertainment.
