⭐ Core Definition: Isotopes of nitrogen

Natural nitrogen (7N) consists of two stable isotopes: the vast majority (99.62%) of naturally occurring nitrogen is nitrogen-14, with the remainder (0.38%) being nitrogen-15. Thirteen radioisotopes are also known, with atomic masses ranging from 9 to 23, along with three nuclear isomers. All of these radioisotopes are short-lived, the longest-lived being N with a half-life of 9.965 minutes. All of the others have half-lives shorter than ten seconds. Isotopes lighter than the stable ones generally decay to isotopes of carbon, and those heavier beta decay to isotopes of oxygen.

Nitrogen-13 is a positron emitter and one of the main isotopes used in medical PET scans.

👉 Isotopes of nitrogen in the context of Isotopes of carbon

Carbon (6C) has 14 known isotopes, from
C to
C as well as
C, of which only
C and
C are stable. The longest-lived radioisotope is
C, with a half-life of 5700 years. This is also the only carbon radioisotope found in nature, as trace quantities are formed cosmogenically by the reaction
N + n →
C +
H. The most stable artificial radioisotope is
C, which has a half-life of 20.34 min. All other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. Lighter isotopes exhibit beta-plus decay into isotopes of boron and heavier ones beta-minus decay into isotopes of nitrogen, though at the limits particle emission occurs as well.

Isotopes of nitrogen in the context of Oxygen-18

There are three known stable isotopes of oxygen (8O):
O,
O, and
O. Radioisotopes are known from O to O (particle-bound from mass number 13 to 24), and the most stable are
O with half-life 122.27 seconds and
O with half-life 70.62 seconds. All remaining radioisotopes are even shorter in lifetime. The four heaviest known isotopes (up to
O) decay by neutron emission to
O, whose half-life is 77 milliseconds; O, along with Ne, have been used in the model of reactions in the crust of neutron stars. The most common decay mode for isotopes lighter than the stable isotopes is β decay to nitrogen, and the most common mode after is β decay to fluorine.
