WebOne of the special qualities of radiogenic Pb-U-Th geochemistry is the coexistence of three daughter-parent (D/P) systems: ²⁰⁶Pb/²³⁸U, ²⁰⁷Pb/²³⁵U, and ²⁰⁸Pb/²³²Th. The uranogenic pair of D/P systems are coupled chemically so that they lead to rigorously linked isotope ratio variations during disturbance. WebThe radioactive isotope 235U decays to the stable daughter isotope 207Pb with a half-life of 713 million years. If you analyze a rock in the laboratory and find it contains 50 parts 235U and 750 parts 207Pb, What is the age of the rock?

WebOct 29, 2024 · The total mass is 4. When an alpha particle is emitted the mass number goes down by 4 and the atomic number goes down by 2. So 214 − 4 = 210 for the mass number 84 −2 = 82 for the atomic number. 82 is the atomic number of Lead, Pb, so the equation is 214 84 Po → 210 82 Pb+ 4 2He Answer link There are three stable "daughter" Pb isotopes that result from the radioactive decay of uranium and thorium in nature; they are Pb, Pb, and Pb. Pb is the only non-radiogenic lead isotope, therefore is not one of the daughter isotopes.
