A beta particle is made up of a positron or an electron that has been emitted when an atom undergoes beta decay. Beta particle emission is different from alpha and gamma radiation, which consist of helium nuclei and high...
A beta particle is an electron emitted from the nucleus of an atom that has undergone beta decay. The electron is called a beta particle as a way of distinguishing it from the electrons present in the atom's shell.
According to Encyclopædia Britannica, a beta particle can have either a negative charge (if it is an electron) or a positive charge (a positron). Beta particles are emitted by unstable atomic nuclei. The emission of beta...
An electron is a negatively charged sub-atomic particle that is located in an atom along with protons and neutrons. The electrons are found in shells and sub-orbitals that surround the nucleus of the atom.
The electron is the lightest particle of the atom. It has a mass of 9.1 x 10-28 grams. Comparing this mass to that of the proton's at 1.6726 x 10-24 grams, an electron is nearly 0.0005 times the proton's mass.
A negatively charged particle within an atom is called an electron. Electrons were discovered in 1897 by a British scientist named J.J. Thomson.
An atom becomes a positive ion when it loses an electron, which is a negatively charged subatomic particle. Only metal atoms can become positive ions.
