The radioactive isotope content of a rock can be used to identify which property of the rock?.
Answer:
The radioactive isotope content of a rock can be used to identify the rocks age.
The radioactive isotope content of a rock can be used to identify the rocks age.
What is radioactive isotope?Any of multiple species of the same chemical element with varying masses whose nuclei are unstable and spontaneously emit radiation in the form of alpha, beta, and gamma rays to waste excess energy is referred to as a radioactive isotope, radionuclide, or radioactive nuclide.
The nuclear decay of radioactive isotopes is a clock-like process and thus a useful tool for determining the absolute age of rocks. These isotopes decay within the rocks according to their half-life rates, and the date at which the rock crystallized can be determined by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them.
Therefore the age of the rock can be identified by the use of the radioactive isotope.
