Which of the following are radioactive decay processes used to determine the age of samples? Select the TWO answers that are correct. a. lead-206 to bismuth-166b. argon-40 to potassium-40c. carbon-14 to carbon-12d. carbon-14 to nitrogen-14e. potassium-40 to argon-40

d. carbon-14 to nitrogen-14

e. potassium-40 to argon-40

Explanation:

Radioactive or radiometric dating is a process used by scientists to date materials including rocks and carbon using the decay rate of radioactive isotopes. Certain elements are used in this process, they include: Uranium-238 to lead-206, Pottasium-40 to Argon-40, Carbon-14 to Nitrogen-14 etc.

Uranium-238 to lead-206 is used for uranium-containing minerals with Uranium-238 decaying to lead-206. It has a half-life of 4500 million years.

Pottasium-40 to Argon-40 is used for pottasium-containing materials with pottasium-40 decaying to Argon-40. It has a half-life of 1300 million years

Carbon-14 to Nitrogen-14 is used for carbon-based materials with Carbon-14 decaying to Nitrogen-14. It has a half-life of 5730 million years.
