Izotópösszetételének

Izotópösszetételének refers to the isotopic composition of a substance. Isotopes are atoms of the same element that have different numbers of neutrons, and thus different atomic masses. Every naturally occurring element exists as a mixture of its stable isotopes, and their relative abundances define the isotopic composition of that element. For example, carbon is primarily found as carbon-12 and carbon-13, with trace amounts of radioactive carbon-14. The specific ratio of these isotopes is its isotopic composition. This composition can vary slightly depending on the origin and history of the sample. For instance, the isotopic composition of water can reveal information about its source, whether it's from a glacier, a river, or precipitation. Similarly, the isotopic composition of trace elements in geological samples can help scientists understand the formation and evolution of the Earth. Measuring and analyzing isotopic composition is a powerful tool in various scientific disciplines, including geology, environmental science, archaeology, and forensics, allowing for tracing origins, dating materials, and understanding natural processes. Changes in isotopic composition can also be indicative of physical or chemical processes, such as evaporation, precipitation, or metabolic activity.
