Gravity is still pulling on the balloon, which is why it can't leave our atmosphere. The helium balloon will rise until it meets an elevation that has the same density as itself. The balloon will just hover in place.
If you look at helium... It's lighter than oxygen. If you pumped both helium and oxygen in a room, the helium would fill up the top half because it's lighter, and the oxygen would fill up the bottom half of the room because oxygen is heavier than helium.
Helium floats on top of oxygen, much like how an oil spill will float on top of water. Because water is heavier and more dense than oil.

Ok then. You proved me wrong.
Please don't breed.
Helium is lighter than air.
