Alpha Decay
Alpha decay, a fundamental process in nuclear physics, involves the emission of an alpha particle from the nucleus of an unstable atom. This phenomenon plays a crucial role in the natural radioactive decay of certain elements, leading to the transformation of one element into another. The emitted alpha particle consists of two protons and two neutrons, symbolizing a helium-4 nucleus. This brief yet potent introduction sets the stage for an exploration of the principles and significance of alpha decay in understanding the behavior of radioactive isotopes.
