A Guide To Alpha Decay Including Equations And Uses Science Drill V. t. e. alpha decay or α decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and thereby transforms or "decays" into a different atomic nucleus, with a mass number that is reduced by four and an atomic number that is reduced by two. an alpha particle is identical to the nucleus of a helium.

Understanding the types of radioactive decay that atoms undergo is a crucial part of learning nuclear chemistry. this course from prof. amanda holton reviews the differences among alpha, beta, and gamma decay, as well as the differences in nuclear fission and fusion. also covered is how to predict the type of decay an atom will undergo. Uranium 238 decay: one of the most well known examples of alpha decay is the decay of uranium 238. it decays through alpha emission to form thorium 234 according to the equation: ^{238} 92u → ^{234} {90}th ^4 2he. radium 226 decay: another example of alpha decay is radium 226 decaying to radon 222. this is described by the equation:.
