Question
What kind of radioactive element is useful for dating an object?A.One that is present in very small amountsB.One that does not undergo transmutationC.One that decays very quickly into a stable formD.One with a half-life close to the age of the object
Solution
D. One with a half-life close to the age of the object
This is because radioactive dating works by comparing the ratio of the original radioactive element (or parent isotope) to its decay products (or daughter isotopes). If the half-life of the radioactive element is close to the age of the object, it means that enough time has passed for a significant amount of the parent isotope to decay, but not so much time that all of it has decayed. This makes it possible to accurately determine the age of the object.
