Question: Which isotope is most commonly used in the radioactive dating of fossils?

There are several common radioactive isotopes that are used for dating rocks, artifacts and fossils. The most common is U-235. U-235 is found in many igneous rocks, soil and sediment. U-235 decays to Pb-207 with a half-life of 704 million years.There are several common radioactive isotopes

What isotope is used to date fossils?

carbon-14 dating Radiocarbon dating method Radiocarbon dating is also simply called carbon-14 dating. Carbon-14 is a radioactive isotope of carbon, with a half-life of 5,730 years (which is very short compared with the above isotopes), and decays into nitrogen.

What is one of the most commonly used radioactive isotopes used in dating archeological artifacts?

carbon-14, the longest-lived radioactive isotope of carbon, whose decay allows the accurate dating of archaeological artifacts. The carbon-14 nucleus has six protons and eight neutrons, for an atomic mass of 14.

Which radioactive isotope is used in dating techniques?

Radiocarbon (14C) Radiocarbon (14C) dating All living organisms take up carbon from their environment including a small proportion of the radioactive isotope 14C (formed from nitrogen-14 as a result of cosmic ray bombardment).
