Cultural Dictionary
electron [(i-lek-tron)]

An elementary particle with a negative charge and a very small mass. Electrons are normally found in orbits around the nucleus of an atom. The chemical reactions that an atom undergoes depend primarily on the electrons in the outermost orbits (the valence electrons).

Note: The movement of large numbers of electrons through conductors constitutes an electric current.
