Scrabble?! NONCOMPOUND

Definitions of NONCOMPOUND in various dictionaries:

Neon compounds were long believed not to exist. Neutral neon-containing molecules were only discovered in the twenty-first century, and even today are not well known. Neon is a noble gas with a high first ionisation potential of 21.564 eV, which is only exceeded by that of helium (24.587 eV). This means that ionic compounds use too much energy to make. Neon's polarisability of 0.395 Å3 is the second lowest of any element (only helium's is more extreme). Low polarisability means there will be little tendency to stick to other atoms. Neon has a Lewis basicity or proton affinity of 2.06 eV. However, there are molecular ions which contain neon, as well as temporary excited neon-containing molecules called excimers. Several neutral neon molecules have been predicted to be stable, but have not yet been found to exist. Neon has been shown to crystallise with other substances to form clathrates or Van der Waals solids.
