How does Protactinium contribute to our understanding of Earth's history and the behavior of elements in natural systems?

Answer Posted / Pooja Saini

Protactinium isotopes, particularly Pa-231 and Pa-235, are used as geochronometers to date minerals and rocks. The half-life of these isotopes allows scientists to determine the age of samples ranging from a few thousand years to billions of years. This information can provide insights into Earth's geological history, including plate tectonics, continental drift, and the formation of ores.n
