Quibble: Argon does not form molecule, being an inert gas. However having the same number of shells as nitrogen, but more protons, its electron are more tightly bound and hence have a slightly smaller outer orbital. As for oxygen, the molecule might be a tiny bit smaller, but the more important fact for leakage is that both nitrogen and oxygen molecules are essentially tiny rods, so that they have to strike end-on at just the right place to leak through.

But basically the leakage claim is just stupid.
