Science definitions for negatron (1 of 2)

negatron

[ nĕg′ə-trŏn′ ]

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.

Science definitions for negatron (2 of 2)

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.

Culture definitions for negatron

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.
