The half-life of radioactive isotopes is unaffected by any environmental factors, so the isotope acts like an internal clock. For example, if a rock is analyzed and is found to contain a certain amount of uranium-235 and a certain amount of its daughter isotope, we can conclude that a certain fraction of the original uranium-235 has ...
Chemistry Mr. Nguyen Half-Life of Radioactive Isotopes: Answers 1. How much of a 100.0 g sample of Au-198 is left over after 8.10 days if its half-life is 2.70 days? Ans: 12.5 grams Use the formula: final mass = initial mass x (1/2) n, where n = total time / half-life. In this case, n = 8.10 days / 2.70 days = 3.
