A radioactive nucleus consists of an unstable assembly of protons and neutrons which becomes more stable by emitting an alpha, a beta particle, or a gamma photon. An alpha particle is identical to the nucleus of a helium atom, which comprises two protons. Alpha decay will cause transmutation to occur - this means that one element will turn into another element as the alpha particles are released. However, none of the isotopes of hydrogen has the requisite number of protons and neutrons in its nucleus to emit an alpha particle. The alpha particle is called a helium atom that has lost two electrons and carries a + 2e charge. This particle, also known as an alpha particle, consists of two protons and two neutrons.
