and sugar cubes to simulate the radioactive decay of different isotopes. A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different ...

Some commonly used dating methods are summarized in Table 1. The rate of decay for many radioactive isotopes has been measured and does not change over time. Thus, each radioactive isotope has ...
