Lead-207 is called the daughter of uranium-235. What does this mean? carbon-14 nitrogen-14 5730 up to 50 000 23. How old is a rock sample that oontains uranium-235 and lead-207 in equal amounts? 24. The age of Earth was first established in 1953 when Claire C. Patterson of the California Institute of Technology used a uranium-lead clock to analyze rock. In comparing amounts of uranium-235 with lead-207, he established that about 8 half-lives of uranium-207 had passed since the rock formed. Using this data, estimate the age of Earth. 25. lodine-131 is a radioactive substance that can be used to treat certain thyroid conditions. It has a half-life of 8…
