ELECTRONS

Stable elementary particles having the smallest known negative charge, gift in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons near atomic nuclei determine the chemical identities of elements. Beams of electrons are called cathode rays or beta rays, the latter being a high-energy biproduct of nuclear decay.
