aThe charge of an electron or of a proton is much too small to be basic quantity of charge of charge for almost all practical applications. The SI unit of charge is the coulomb, with the symbol C. A coulomb of negative charge equals that of 6.242(1018 electrons. The coulomb is a deriv...
ELECTRON:The electron is a subatomic particle carrying a negative electric charge. It has no known components or substructure. Therefore, the electron is generally believed to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton[9] ...
