Because any element used in the cathode produced electrons, scientists concluded that all atoms contained electrons.
The electrons are produced on the cathode through thermionic emission and are expanded in the direction of the display by using the cathode that is linked to the terminal of the extra high anxiety battery. Thermionic emission is the method wherein metallic surfaces emit electrons while heated.
Thomson invented the electron by means of gambling with a tube that changed into Crookes, or cathode ray. He had proven that the cathode rays had been charged negatively. Thomson realized that the well-known version of an atom no longer accounts for the debris charged negatively or undoubtedly.
