Alpha Particle
A positively charged particle emitted from the nuclei of certain
atoms during radioactive disintegration. The alpha particle has
an atomic weight of 4 and a positive charge equal in magnitude
to 2 electronic charges; hence it is essentially a helium nucleus
(helium atom stripped of its two planetary electrons). Compare
beta particle,
gamma ray.
