Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways. Alpha particles are named after the first letter in the Greek alphabet, Î±. The symbol for the alpha particle is Î± or Î±2+. Because they are identical to helium nuclei, they are also sometimes written as He2+ or 4 2He2+ indicating a helium ion with a +2 charge. If the ion ...
Alpha, beta and gamma radiation can be emitted from any unstable nucleus of an atom. An alpha particle is essentially a helium nucleus. Under certain conditions, a large nucleus may give off these particles. An alpha particle is two protons and two neutrons. An alpha particle has a positive charge. An alpha particle in isotopic notation looks like this: Alpha particles are very large in comparison to beta and gamma. An alpha particle has very low penetrating ability. People can protect themselves against an alpha particle by using a sheet of paper, which will deflect the alpha particle. Human skin is not affected by alpha particles.
