when electrons leave an atom during static electricity how are they replaced???

The atoms remain ionized (charged) until the source of electrons is restored. If the material in question is a perfect dielectric, it can remain charged forever. Most real-world materials, however will eventually "leak" back to their uncharged state.

 

There are vast source of electrons out there, I'll bet even the solar wind has some. They will find a source somewhere.
