Decay Chains is the name given to the stages of radioactive decay of unstable isotopes or elements. Some radioactive isotopes decay into stable isotopes directly but some unstable or radioactive isotopes decay into other unstable isotopes many times before becoming stable and these stages are explained in the ‘decay chain’. These decay chains can
