Nitrogen-14 is one of two stable (non-radioactive) isotopes of the chemical element nitrogen, making up 99.636% of natural nitrogen.
It is one of the few stable nuclides with both an odd number of protons and neutrons (7 each) each of which contributes spin 1/2 each giving the nucleus a magnetic spin of 1.

Nitrogen-14 is one of two stable (non-radioactive) isotopes of the chemical element nitrogen, making up 99.636% of natural nitrogen.
It is one of the few stable nuclides with both an odd number of protons and neutrons (7 each) each of which contributes spin 1/2 each giving the nucleus a magnetic spin of 1.
Like all elements heavier than helium, the original source of nitrogen-14 in the universe is believed to be stellar nucleosynthesis, where it is produced as part of the CNO cycle.
It is the source of naturally-occurring carbon-14; cosmic radiation interacts with nitrogen-14 in the upper atmosphere creating C, which eventually decays back to N.
