isotopic composition

Isotopic composition refers to the relative abundance of different isotopes of an element in a sample. Isotopes are versions of an element that have the same number of protons but different numbers of neutrons. This variation can affect the element's atomic mass and some of its properties. For example, carbon has stable isotopes like carbon-12 and carbon-13. Scientists analyze isotopic composition for various purposes, such as determining the age of artifacts in archaeology or studying climate changes in environmental science, as different isotopes can provide insights into processes and origins.
