Cultural definitions for electron

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).

notes for electron

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

Scientific definitions for electron

electron

[ ĭ-lĕk′trŏn′ ]

A stable elementary particle in the lepton family having a mass at rest of 9.107 X 10-28 grams and a negative electric charge of approximately 1.602 X 10-19 coulombs. Electrons orbit about the positively charged nuclei of atoms in distinct orbitals of different energy levels, called shells. Electrons are the primary charge carriers in electric current. Compare positron. See also electromagnetism elementary particle ion. See Table at subatomic particle.

A positron or a negatron.
