The stable isotopes of nitrogen are:
- Nitrogen-14 (14N): This is the more abundant of the two stable isotopes, comprising approximately 99.63% of naturally occurring nitrogen.
- Nitrogen-15 (15N): This is the less common stable isotope, making up the remainder of naturally occurring nitrogen, approximately 0.37%.
These isotopes play a crucial role in various processes, including physical, chemical, and biological processes, and their relative abundances can be used to study the origin and transformation of nitrogenous materials within and between different reservoirs.
