Borrowed from English -on, a suffix extracted from argon, krypton and neon, the first three noble gases to be named, respectively from Ancient Greek ἀργόν (argón, “lazy, inactive”), κρυπτόν (kruptón, “hidden”) and νέον (néon, “new”); hence, ultimately from Ancient Greek -ον (-on), cognate with Latin -um.

-ón m (noun-forming suffix, plural -ones)

1. (chemistry) ending of every chemical element belonging only to the noble gases group, except helium (in Spanish helio)
