subject, “A sub-atomic particle which is a fundamental constituent of all matter having a mass 1/1837. Please Provide following information to Register, Theories and Experiments Related to Struct. As the droplet falls to the bottom of the chamber, it passes between two electrically charged plates. It may be either equal to or integral multiple of the charge on an  electron. Thus charge on an electron = 1.602 x 10–19C. The rays ionize a gas through which they pass. They rotate a light wheel placed in their paths. In 1932, Chadwick bombarded the element Beryllium with a-particles and noticed the emission of a radiation having the following characteristics. Their path is independent on the position of the anode. “A sub-atomic particle which is a fundamental constituent of all matter having a mass 1/1837th of a H-atom and which carries the smallest unit of negative charge is called an electron”. askiitians.

The removed electrons constitute the cathode rays and the positive residues form the positive or canal rays. These rays are called “Cathode Rays”. Positive rays are atomic or molecular resides from which some electrons have been removed.
