Isotope dating of rocks getprofileu
This process of changing the isotope of one element (designated as the parent) into the isotope of another element (referred to as the daughter) is called radioactive decay.
Thus, the parent isotopes that decay are called radioisotopes.
These parent radioisotopes change into daughter lead-206, lead-207, argon-40, strontium-87, and neodymium-143 isotopes, respectively.
Isotopes are used as tracers in many medical settings.
Radioactive isotopes are used to identify abnormal bodily processes.
Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).
The atoms in each chemical element may vary slightly in the numbers of neutrons within their nuclei.
Geologists must first choose a suitable rock unit for dating.
