I think a solid 'dissolved' in another solid is an alloy, e.g. steel (Fe and C), brass (Zn and Cu) tho' they have to be melted first. BTW something funny happens with ethanol and water since they can't ultimately be separated by distillation (let alone gravity fields) because of the formation

Another example of a top-of-the-atmosphere special layer is of course the ozone (O3) layer, continually produced by ultraviolet light but unstable. These surface phenomena don't have anything to do with how nitrogen, oxygen, and uranium hexafluoride are distributed throughout the atmosphere.

Huh? That makes no sense. Moreover, there is NO hydrogen or helium in our atmosphere. Any that we might have once had is long gone. Given the very large average height and correspondingly high average speed (and much higher speed in the high-speed tail of the distribution), these very-low-mass

For a start the density of oxygen is higher than nitrogen. Secondly gravity is not strong enough to overcome the zipping around of the molecules of gas that naturally mix together due to thermal energy (temperature). It takes a lot of effort and processing to separate atmospheric gasses (see
