Here's a breakdown:
* Identical chemical behavior: Isotopes of the same element have the same number of protons and electrons, making them behave almost identically in chemical reactions. This means a radioactive isotope (radiotracer) will participate in the reaction just like its non-radioactive counterpart.
* Distinct nuclear properties: Radioactive isotopes emit radiation, allowing us to track their movement and fate within the reaction. This radiation can be detected using specialized equipment, providing insights into the reaction pathway and the involvement of specific atoms.
In summary: Radiotracers act like "invisible spies" in chemical reactions. They participate in the reaction like normal atoms, but their unique radiation signature lets us follow them throughout the process, revealing valuable information about how the reaction proceeds.
