Beta particles are?

Explanation:
Beta decay involves a neutron transforming into a proton and emitting an electron (plus an antineutrino). The electron that’s emitted is the beta particle—it's a fast-moving, negatively charged particle that comes from the nucleus. This distinguishes it from protons (positively charged), neutrons (uncharged), and photons (massless light). So beta particles are fast-moving electrons emitted from the nucleus.
