Subject: What is the definition of empty space within the atom and between atoms?

I resubmit this question!  In searching the Mad Science archives there are
several conflicting answers. The most meaningfull was id 894511435.ph 
If a hydrogen atom was the size of the superdome,the nucleus would be the 
size of a marble and the electron the size of a grain of sand the rest is 
empty space!! Perhaps several of your Mad Scientists could arrive at a
common answer.This is a fundamental question not found in the text books.
