Uranium-238 decays to type lead-206 with a half-life of 4.forty seven billion years. Uranium-235 decays to kind lead-207 with a half-life of 704 million years. Potassium-40 decays to argon-40 with a half-life of 1.26 billion years. Therefore any argon that’s found in a crystal most likely fashioned as a outcome of the decay of potassium-40. Measuring the ratio of potassium-40 to argon-40 will yield a great estimate of DatingRank the age of the sample.
