Would you like to make it the primary and merge this question into it?

exists and is an alternate of .

Osmium This is totally incorrect. Osmium has the tenth highest melting point of all elements and therefore cannot be a gas at room temperature. Radon is heavier and also a gas. The atomic weight of radon is 222 atomic mass units making it the heaviest gas known. It is also radioactive and can collect in basements/cellars of homes. From Wikipaedia :: According to the United States Environmental Protection Agency, radon is the second most frequent cause of lung cancer, after cigarette smoking, causing 21,000 lung cancer deaths per year in the United States......

Is nonane gas at room temperature?

Yes. ********************** 2nd Opinion: No. The alkanes are liquids at room temp. and pressure starting with pentane, C5H12. Since nonane, C9H20, is beyond that, it has to
