An electron is one of the fundamental subatomic particles which exists with a negative electrical charge and an extremely small mass when compared to protons and neutrons. It is a lepton with a rest mass of
lbs and carries the fundamental charge of
C, and a hypercharge of -1. An electron has a spin of approximately 1/2 and obeys Fermi-Dirac Statistics.[1] Electron pairs within an orbital system have opposite spins due to the Pauli Exclusion Principle; this characteristic spin pairing allows electrons of the same quantum orbital to exist together, as the opposing magnetic dipole moments induced by each of the electrons ensures that they are attracted together.
