Question

Which isotope is used to find the age of prehistoric objects?

Answer 1

Answer:

Radiocarbon dating

Explanation:

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.

Answer 2

Radiocarbon dating makes use of the radioactive isotope of Carbon or C-14 in order to estimate the age of prehistoric orbits. Carbon-14 present is compared with the other isotopes of carbon (C-12 and C-13) to find out how much it has decayed radioactively. Carbon-14 decays radioactively by half every 5730 years approximately, so the age of different prehistoric objects can now be estimated by finding out the extent to which the C-14 has decayed.
