Inert gases are different from noble gases both in the intension and the extension.
The term "inert gas" does not mean the first six members of Group 18 on the periodic table. Noble gases, nitrogen gas and even some compound gases are called inert gas depending on context, though some heavier noble gases, as well as nitrogen, react with other substances under certain conditions.
On the other hand, the term "noble gas" means exactly the first six members of Group 18 on the periodic table. The ununoctium, a member of Group 18, may not be a member of noble gas because of its chemical properties.
Guessing from the etymology "neon" and the examples of x2 [neon/argon/radon/xenon/krypton], the creator of this gismu seems to intend to define {navni} as "noble gas", not "inert gas". If not, by any chance, "nitrogen", the most familiar inert gas under ordinary conditions, should have been listed as an example of x2, or "radon/xenon/krypton" are not very appropriate in some contexts.
gismu for "noble gas" is more useful than "inert gas", because the latter is easily expressed with lujvo {tolfragapci}. In conclusion, I recommend to correct this error by replacing "inert" with "noble".
