What is Alpha Decay?
Alpha decay is a type of radioactive decay where an unstable atomic nucleus emits an alpha particle, which consists of two protons and two neutrons (essentially a helium-4 nucleus). This process results in the transformation of the original nucleus into a new element, with an atomic number reduced by two and a mass number decreased by four. The emission of alpha particles is central to explaining the radioactivity of heavy elements like uranium, radium, and thorium.
