Suppose you have a helium balloon. After having it for a while it will deflate. Where does that helium go without a hole in the balloon?

The balloon is not always air tight.
A little by little amount of helium gets out.
The Helium then diffuse in the midair while rising up. Because Helium is lighter than air itself.

Helium is an extremely small molecule. If you were to examine the skin of the balloon under a powerful microscope, you would find that there are tiny holes all over it. Because helium is so small, it can slowly pass through the small holes in the balloon membrane and escape to the atmosphere.

In agreement with "dogsafire" above....in fact helium has such a small molecule that it even diffuses thru pyrex glass test tubes.
This is also a problem with hydrogen. If it is put into a steel welded tank it actually diffuses into the metal, especially at high pressures, and affects the strength properties of the steel, particularly the welds.

The balloon is not perfectly air tight. The ballon will slowly deflate itself.
