Nitrogen-14 is a stable, non-radioactive isotope of the chemical element nitrogen.

Nitrogen-14 comprises approximately 99% of all naturally formed nitrogen. It is the source of naturally-occurring carbon-14, which is created when cosmic radiation interacts with nitrogen-14 in the upper atmosphere. It is also formed from the radioactive decay of carbon-14. However, like all elements heavier than helium, the original source of nitrogen-14 in the universe is believed to be stellar nucleosynthesis. It is produced as part of the CNO cycle of stellar nuclear reactions. An odd number of protons and neutrons (7 each) contribute 1/2 spin each giving the nucleus a magnetic spin of 1.
