A neon compound is still yet to be theoretically identified although the gas phase ions like NeAr+, NeH+, HeNe+have been resolved from mass spectrometry studies.
The average atomic mass of neon is 20.1797 u. Neon is known to have over nineteen different isotopes ranging from 16-34 in isotopic mass. However, neon only has three stable isotopes: 20Ne, 21Ne, and 22Ne. The most abundant of those stable isotopes (no t1/2 or decay) is 20Ne at about 90% via alpha decay of Mg-25 to form Ne-21.
