Chapter 39, Problem 22A
What isotopes accumulate in old, uranium-bearing rock?
Expert Solution & Answer
To determine
The name of the isotope accumulate in the old uranium bearing rock.
Explanation of Solution
Introduction:
The carbon dating cannot predict the age of very old objects. The prediction of age of very old objects is accomplishes by the radioactive material Uranium. The prediction of age on the basis of Uranium content in the object is called Uranium dating.
The half-life radioactive material uranium is very high. So, uranium decays very slowly. Uranium coverts into the isotopes of lead at the end of decay process. The isotopes of lead Pb-206 and Pb-207 exist simultaneously.
The higher the percentage of lead isotopes in the bearing rock older is the uranium bearing rock.
Conclusion:
Thus, the isotopes of lead Pb-206 and Pb-207 accumulate in the old uranium bearing rock.
