WebThe time it takes for half of the atoms in a substance to decay is called the half-life. In other words, the half-life of an isotope is the amount of time it takes for half of a group of unstable isotopes to decay to a stable isotope. The half-life is constant and measurable for a given radioactive isotope, so it can be used to calculate the ...

WebThe half-lives of different isotopes can be very differ-ent. Some parent isotopes have half-lives of more than 4 billion years. Others have half-lives of only about 6,000 years. Very old rocks can be dated only if isotopes with long half-lives are used. Very young rocks can be dated only if isotopes with short half-lives are used. WebJan 8, 2024 · Determine the most appropriate absolute dating method to determine the ages of the materials in the following questions. Hint: refer to the section on radiometric dating in the overview section of this textbook for half-life values for various radiometric dating methods and examples of how to complete these problems. 14.
WebOct 13, 2024 · Answer: A half-life is the amount of time that it takes for half of the given radioactive parent isotope to decay into a stable daughter product. By comparing the amount of radioactive parent isotope in remains to the stable daughter product, an absolute age may be determined. WebAn isotope's half‐life is the time it takes for half of a known quantity of radioactive material to convert to its daughter product. For example, the half‐life of U‐238 is 4.5 billion years. Thus, if you began with one gram of U‐238, 4.5 billion …
