I havn't measured if its losing helium so i'm not sure. I just go with what I know and can observe or test.
I agree that it has to do with density, but if there's no barrier like a dome then the topmost gasses would get sucked into "space" since gravity can't hold them down against the force of a vacuum.
Or the entire atmosphere.

I thinkbit might be like that kid's experiment. You disolve different amounts of sugar in to 3 different samples of water. In each sample you add a different food colouring to the solution.
The liquids separate into layers by density, but that doesn't mean the lightest liquid floats away out of the cup (again excepting evaporation). Gas might be similar? But perhaps not as otherwise perhaps we'd end up with different layers for nitrogen/oxygen/etc.
What doesn't stop that happening? Weather axing as a mixer? If so, how do the light gases not remain stirred in?
All excellent questions you are leading to.
