Generally (not always), even elements form molecules.  Oxygen definitely
forms O2 (meaning two atoms of oxygen per molecule) or O3 (which is ozone
and rapidly degrades to O2); and ISTR that nitrogen forms N2 normally.

But I don't think you can look at molecule size (or atom size) and form
meaningful conclusions about permeability.  At least that's not the way I
remember it.
