Isotopic abundance
Definition of isotopic abundance
Isotopic abundance refers to the relative proportions of different isotopes in a sample of an element. It is a measure of how common or rare each isotope is compared to the others. Isotopic abundance is expressed as a percentage or a fraction.
Calculation of isotopic abundance
Isotopic abundance is determined by comparing the mass of each isotope to the total mass of all isotopes of an element and calculating the percentage or fraction.
The calculation involves multiplying the mass of each isotope by its abundance, summing the results for all isotopes, and then dividing each individual result by the total mass of all isotopes. This yields the percentage or fraction of each isotope in the sample.
For example, let’s consider the element carbon with its two stable isotopes, carbon-12 and carbon-13. Carbon-12 has a mass of 12 atomic mass units (amu) and an abundance of 98.93%. Carbon-13 has a mass of 13 amu and an abundance of 1.07%. To calculate the isotopic abundance of each isotope, we multiply the mass of each isotope by its abundance and divide by the total mass of both isotopes. The isotopic abundance of carbon-12 is (12 amu * 98.93%) / (12 amu + 13 amu) ≈ 98.40%, while the isotopic abundance of carbon-13 is (13 amu * 1.07%) / (12 amu + 13 amu) ≈ 1.60%.
Examples of isotopic abundance in elements
Isotopic abundance varies among different elements and isotopes. Some elements have only one stable isotope, so their isotopic abundance is 100% for that particular isotope. For example, hydrogen has two isotopes, protium and deuterium, with isotopic abundances of approximately 99.986% and 0.015%, respectively.
Other elements, such as oxygen, have multiple stable isotopes, each with its own isotopic abundance. Oxygen-16 is the most abundant isotope, with an isotopic abundance of about 99.759%. Oxygen-17 and oxygen-18 have isotopic abundances of approximately 0.037% and 0.204%, respectively.
Isotopic abundance can also vary within a given element due to natural processes or human activities. For example, carbon-14 is a radioactive isotope of carbon, which is used for radiocarbon dating. It has a very low natural abundance of about 1 part per trillion, but its isotopic abundance can be increased artificially through nuclear reactions.
