WebMar 17, 2024 · To measure the age of plant and animal remains from the more recent past, scientists use a radioactive isotope of carbon, called carbon-14, as their clock. As carbon-14 decays, with a half-life of about … WebForms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons …
WebApr 16, 2024 · Absolute dating or radiometric dating is a method used to determine the age of rocks by measuring its radioactive decay. A radioactive isotope in the rock decays into a stable daughter isotope. The decay occurs at a predictable rate, so the age of the sample could be determined. WebOther radiometric dating techniques are available for earlier periods. One of the most widely used is potassium–argon dating (K–Ar dating). Potassium-40 is a radioactive isotope of potassium that decays into argon-40. The half-life of potassium-40 is 1.3 billion years, far longer than that of carbon-14, allowing much older samples to be dated.
