How do scientists figure out the age of a substance using radiometric dating?

It's based on the natural radioactive decay of certain elements, such as potassium and carbon.

Explanation:

To establish the age of a rock or a fossil, researchers or scientists use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.
