The half life of a radioactive isotope is the amount of time it takes for half of the isotopes to decay. Similarly, the elapsed time t and the initial quantity n (0) of a radioactive isotope can also be calculated by following the same process. A block of radioactive material will contain many trillions of nuclei and not all nuclei.
