Question

which correctly lists the three isotopes that geologists measure to determine the age of an organisms argon, nitrogen, and carbon - 12 carbon - 14, nitrogen, and carbon - 12 nitrogen, potassium, and carbon - 14 carbon - 12, potassium, and argon

Explanation:

Carbon - 14 is used in radiocarbon dating. Carbon - 12 is a stable isotope and is used as a reference. Nitrogen is a by - product in the decay of carbon - 14 ( \(^{14}C
ightarrow^{14}N + e^{-}+\overline{
u}_{e}\) ). Geologists measure these three isotopes for age determination of organisms.

Answer:

carbon - 14, nitrogen, and carbon - 12
