Alpha radiation, one of the main types of radiation released during radioactive decay, consists of particles that are equivalent to the nucleus of which element?

Explanation

Alpha radiation consists of alpha particles, which are structurally identical to the nucleus of a helium atom, containing two protons and two neutrons bound together. Among the common types of radioactive decay, alpha particles have relatively low penetrating power, meaning they can typically be stopped by something as simple as a sheet of paper or the outer layer of human skin, though they can still be quite hazardous if an alpha-emitting substance is inhaled or ingested. Alpha decay occurs when an unstable atomic nucleus emits an alpha particle, transforming into a different, generally more stable, element in the process.
