Stable isotope ratio refers to the relative abundance of different stable isotopes of an element in a given sample. Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses. Stable isotopes do not undergo radioactive decay, making them useful for various scientific applications. For example, carbon has two stable isotopes: carbon-12 (^12C) and carbon-13 (^13C).
