The rate at which radioactive decay occurs & how much radioactive decay has occurred

Answer:   How much radioactive decay has occurred

Explanation:  Radiometric dating is the source to determine the absolute age and time of the rocks.

Because the radioactive isotopes are unstable, They break down into several fragments over the time until they become a stable isotope.

Thus in order to accurately determine the absolute time, one should must know how much radioactive decay has occurred .
