Physics:Isotopes of neon

Template:Infobox neon isotopes
Neon (10Ne) naturally occurs as three stable isotopes: The element Chemistry:Neon does not exist., The element Chemistry:Neon does not exist., and The element Chemistry:Neon does not exist.. Their stated natural abundances are those measured in air.
In addition, 17 artificial radioisotopes have been discovered, ranging from The element Chemistry:Neon does not exist. to The element Chemistry:Neon does not exist., all short-lived: the most stable is The element Chemistry:Neon does not exist. with a half-life of 3.38 minutes. All others are under a minute, and most under a second. The isotopes lighter than the stable ones usually decay to fluorine or oxygen, while heavier ones decay to sodium.
