Can anyone explain to me how a molecule composed of atoms all heavier than either oxygen or nitrogen finds its way to the top of the atmosphere?

Don't be a smartass!

The question has been settled.

I’m really not trying to be a smartass.

Chlorofluorocarbons are made of chlorine, fluorine and carbon. All of which are many time more heavy than either oxygen or nitrogen, but I’m supposed to believe it floats to the stratosphere. This does not make sense (Johnnie Cochran voice)!
