Isotopes of nitrogen

<p>Natural <a href="/facts/Nitrogen/Nf1QpGDz">nitrogen</a> (7N) consists of two stable <a href="/facts/Isotope/KD9B1y6o">isotopes</a>: the vast majority (99.6%) of naturally occurring nitrogen is <a href="/facts/Nitrogen-14/JdTSL0KH">nitrogen-14</a>, with the remainder being <a href="/facts/Nitrogen-15/JdTSL0KH">nitrogen-15</a>. Thirteen <a href="/facts/Radioisotope/5WpCfbdq">radioisotopes</a> are also known, with <a href="/facts/Atomic_mass/J1FJY9MV">atomic masses</a> ranging from 9 to 23, along with three <a href="/facts/Nuclear_isomer/L8DHcqnk">nuclear isomers</a>. All of these radioisotopes are short-lived, the longest-lived being nitrogen-13 with a half-life of 9.965(4) min. All of the others have half-lives shorter than ten seconds, with most of these being below 500 milliseconds. Most of the isotopes with <a href="/facts/Atomic_mass_number/VyBbJ1oI">atomic mass numbers</a> below 14 decay to <a href="/facts/Isotopes_of_carbon/K1LfqDNj">isotopes of carbon</a>, while most of the isotopes with masses above 15 decay to <a href="/facts/Isotopes_of_oxygen/ektDXb8B">isotopes of oxygen</a>. The shortest-lived known isotope is nitrogen-10, with a half-life of 143(36) <a href="/facts/Yoctoseconds/bEovB6Tp">yoctoseconds</a>, though the half-life of nitrogen-9 has not been measured exactly.
