In physics, a daughter is a name used for decay products, leftovers from radioactive decay. It is an isotope that is formed by the collapse of a different isotope, through several successive steps. Other names used for it are daughter product, daughter nuclide or daughter isotope. We can precisely describe it as the nuclide that remained after radioactive decay took place.
In simpler terms, the daughter is the nucleus that remained after the parent nucleus disintegrated. Products that remain after decay like the daughter are extremely important because they help us understand radioactive decay itself. They also prove as a source of information about the best ways to handle radioactive waste.
