The abundances of the naturally occurring isotopes of neon

Neon (10Ne) naturally occurs as three stable isotopes: 20
Ne
, 21
Ne
, and 22
Ne
. Their stated natural abundances are those measured in air.

In addition, 17 artificial radioisotopes have been discovered, ranging from 15
Ne
to 34
Ne
, all short-lived: the most stable is 24
Ne
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.
