Complete the sentence. Select all that apply. A beta particle: is electromagnetic energy is emitted from the nucleus has zero charge has a +2 charge has a -1 charge is an electron

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 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 , 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.
