TLE Electron The electron (symbol: e−) is a subatomic particle with a negative elementary electric charge. An electron has no known components or substructure. It is generally thought to be an elementary particle.[2] An electron has a mass that is approximately 1/1836 that of the proton. The intrinsic angular momentum (spin) of the electron is a half-integer value in units of ħ‚ which means that it is a fermion.
