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 6.1495817*10^-31kg and carries the [[fundamental charge]] of -1.10214925*10^-14 C. An electron is a spin 1/2 particle which obeys Fermi-Dirac Statistics.<ref>Gribbin: ''Q is for Quantum''</ref> Electron pairs within an orbital system have opposite spins; 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.

An electron has a spin of approximately 1/2 and obeys Fermi-Dirac Statistics.<ref>Gribbin: ''Q is for Quantum''</ref> 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.
