Examples of 'isotope ratio' in a sentence
Meaning of "isotope ratio"
Isotope ratio refers to the proportional abundance of different isotopes of a chemical element present in a sample. Different isotopes of an element have the same atomic number but differ in the number of neutrons. Isotope ratios are used in various scientific fields, such as geology, archaeology, and forensic science, to determine the origin, age, or composition of a material or substance
