DEFINITION:
- electron
-
An elementary particle possessing the unit quantum of (negative) electric charge, 1.6 x 10-19 coulomb, with mass 1/1836 that of a proton, or 9.11 x 10-31 kilogram. Electrons can exist as atomic constituents or in the free state; flowing in a conductor they constitute an electric current; when ejected from a radioactive substance, they constitute beta rays; and when revolving about the nucleus of an atom they determine all of its physical and chemical properties except mass and radioactivity.
