Alpha Particles |
||||||
 |
||||||
|

| Alpha particles consist of two protons and two neutrons that act as a single particle. An alpha particle is identical to the nucleus of a Helium atom. When alpha particles are emitted from an unstable radioactive nucleus, the atom is transmuted into a different element. | ||||||
