Answer the following question given this paragraph: Radioactive decay is the breakdown of unstable isotopes into stable elements. For example, carbon-14 is an unstable isotope of carbon that decays to the stable element nitrogen-14. The rate of decay of an isotope is measured in half-lives. A half-life is the time it takes for half a given amount of an isotope to decay. Q: What is the term for the breakdown of unstable isotopes into stable elements? Choices: - isotopic decay - radioactive decrease - secondary decay - radioactive decay A:
radioactive decay
