Answer :
Answer: has a -1 charge
is an electron
is emitted from the nucleus
Explanation:
The beta particle is basically an electron with -1 charge and no mass.
Beta particles are fast-moving electron emitted by radioactive decay of substances. Beta particles have a charge of - 1, and a mass of about [tex]\frac{1}{2000}[/tex] th of a proton. This means that beta particles are the same as an electron.
A beta particle, also called beta ray or beta radiation [tex](\beta)[/tex], is a high-energy, high-speed electron or positron emitted by the radioactive decay of an atomic nucleus during the process of beta decay.
A beta particle is emitted from an atomic nucleus, transforming the original nuclide to an isobar of that nuclide.
