Transcript of Atomic energy!
Block: 1 Atomic Energy(: Radioactive Decay Radioactive decay is the process in which the nucleus of a radioactive atom releases nuclear radiation Alpha Decay Alpha decay us the releasing of an alpha particle from a nucleus. The particles consist of two protons and two nuetrons, so it has a mass number of 4 and a charge of 2+.The process of transforming one element to another is known as transmutation. Alpha particles do not travel far in air before being absorbed; this makes them very safe for use in smoke detectors, a common household item. Beta Decay Beta decay is the relasing of a beta particle from a nucleus.In terms of safety, beta particles are much more penetrating than alpha particles, but much less than gamma particles. THE END!
