Apart from the Noble Gases, ALL of the elemental gases are bimolecular..........

Explanation:

.........i.e. all of the elemental gases are diatomic molecules. Consider, #N_2#, #O_2#, #F_2#, and #Cl_2# ARE ALL diatomic gases.

And all the halogens occur as diatomic molecules; except that bromine is a liquid, and iodine is a gas.

To reflect the molecularity, sometimes you will hear inorganic chemists refer to the bimolecular gases as #"dinitrogen"#, and #"dinitrogen"#.

Note that there also exist a number of heteronuclear diatomic molecules, e.g. #HX#, #NO#, #CO#...........
