A cathode ray
J. J. Thomson is credited with discovering electrons.
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
A device made by J. J. Thomson to detect and process electrons is the Cathode Ray Tube (CRT). Thomson's work with cathode rays led to the discovery of the electron and the development of the CRT, which was crucial in the study of atomic structure and the development of television technology.
J. J. Thomson died on August 30, 1940 from a combination of heart attack and complications related to his deteriorating health. He was 83 years old at the time of his death.
Yes, J. J. Thomson won the Nobel Prize in Physics in 1906 for his discovery of the electron and work on the conduction of electricity in gases.
J. J. ThomsonJ. J. Thomson did the cathode ray experiment where he discovered the existence of electrons.
He sent a cathode ray between electrically charged metal plates.
J. J. Thomson observed that cathod rays are deflected by an electric field - and from this discovered the electron.
J. J. Thomson was born on 1856-12-18.
J. J. Thomson died on 1940-08-30.
Joseph John Thomson.
J. J. Thomson discovered the electron and the isotopes.
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.
It was a scientist named J. J. Thomson.
