You gots the dihydrogen molecule, #H_2#... The physical state of the material depends on the intermolecular interaction between hydrogen molecules....and here this is only a fairly weak dispersion force, which is reasonable because the molecule is certainly non-polar, and is not many electron. The same situation pertains to dioxygen, and dinitrogen, in the air we breathe, in that their intermolecular forces are ALSO weak, tho these are more involatile given that the extra electrons these gases possess results in greater intermolecular interaction.
The result? Dihydrogen, dinitrogen, and dioxygen are ALL room temperature gases. These materials MAY be condensed at VERY LOW temperatures...for hydrogen maybe about #20*K#...
