The table of parent-daughter isotopes shows three different isotope pairs that are used in radioisotope dating. Examine the chart and answer the following questions. Isotope Daughter of Parent Dating Range Half-Life Effective Parent (y) uranium-235 lead-207 710 million>10 million 22. Lead-207 is called the daughter of uranium-235. What does this mean? potassium-40 argon-40 1.3 billion 10 000 to 3 billion 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 Califormia 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.
