[[Neon]] (<sub>10</sub>Ne) possesses three stable [[Isotope|isotopes]]: {{SimpleNuclide|Neon|20}}, {{SimpleNuclide|Neon|21}}, and {{SimpleNuclide|Neon|22}}. In addition, 17 radioactive isotopes have been discovered, ranging from {{SimpleNuclide|Neon|15}} to {{SimpleNuclide|Neon|34}}, all short-lived. The longest-lived is {{SimpleNuclide|Neon|24}} with a half-life of {{val|3.38|(2)|u=minutes}}. All others are under a minute, most under a second. The least stable is {{SimpleNuclide|Neon|15}} with a half-life of {{val|770|(300)|ul=ys}} ({{val|7.7|(3.0)|e=-22|u=s}}). See [[isotopes of carbon]] for notes about the measurement. Light radioactive neon isotopes usually decay to [[fluorine]] or [[oxygen]], while heavier ones decay to [[sodium]].
