Science Dictionary
electron  [%PREMIUM_LINK%]     (ĭ-lěk'trŏn')  Pronunciation Key 
  1. A stable elementary particle in the lepton family having a mass at rest of 9.107 × 10-28 grams and an electric charge of approximately -1.602 × 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.

  2. A positron or a negatron. See more at negatron.

negatron   (něg'ə-trŏn')  Pronunciation Key 
An electron with a negative charge; the antiparticle of the positron. Most branches of particle physics construe each particle along with its antiparticle to be two different forms of one underlying phenomenon, and the term electron is sometimes used as a precisely such a general term, with positron and negatron referring to the forms of the electron as they are manifested in nature. See more at electron.
