The Electron

The Electron is an elementary particle found in the atom.  It is a lepton, and is stable, although it is possible that an electron may decay in 10^26 years (average).  The electron is the basis for the study of orbitals and atomic bonding.  Electrons are so small that their exact location is never determined and, like other particles have a wave form.  The electron has a negative charge (note 4).
