positrones
Scope note: Partículas elementales estables que poseen la menor carga negativa conocida y están presentes en todos los elementos. También se denominan negatrones. Los electrones con carga positiva reciben el nombre de positrones. El número, la disposición y la energía de los electrones alrededor del núcleo atómico determinan la identidad química de los diferentes elementos. La radiación con haces de electrones se denomina RAYOS CATÓDICOS.

Scope note: Stable elementary particles having the smallest known negative charge, present in all elements; also called negatrons. Positively charged electrons are called positrons. The numbers, energies and arrangement of electrons around atomic nuclei determine the chemical identities of elements. Beams of electrons are called CATHODE RAYS.
