Which is not a true statement?
A) Carbon-12 would make an excellent isotope to determine absolute time of a rock because it has a known half-life
B) Carbon-14 would make an excellent isotope to determine absolute time of a rock because it has a known half-life
C) Uranium would make an excellent isotope to determine absolute time of a rock because it has a known half-life
D) Rubidium-87 would make an excellent isotope to determine absolute time of a rock because it has a known half-life

Question

Quizplus · Accepted Answer

Carbon-12 is not a suitable isotope for radiometric dating because it is stable and does not have a half-life. Carbon-14, Uranium, and Rubidium-87, on the other hand, are radioactive isotopes with known half-lives, making them useful for dating purposes.
