You'll get a detailed solution from a subject matter expert that helps you learn core concepts. See Answer Question: 2. WebIn radioactive decay, a parent isotope decays to a daughter isotope. A number of different isotopes undergo serial transformations (decays). When this happens in the case of a very long-lived parent and a short-lived daughter, an equilibrium condition called secular equilibrium develops after about 6 to 7 daughter half-lives. flare drop on coinbase
