Electron


The electron is a low mass particle (1/1836 that of a Proton) with a unit negative electric charge. In simple terms the electrons are said to orbit around the Nucleus of Atoms. Positively charged electrons can also exist, these being known as Positrons. The electron is closely related (identical in fact) to the Beta Particle.
