If there is nothing between electrons and the nucleus in an atom, does the volume the atom occupies consist of a large percentage of nothing?

Ar is nothing between the electrons and the nucleus. electrons are very small, and thus make up a small percentage of the atom’s volume, just like the nucleus. so the difference between a location where there is an atom, and where there is none, is only very minor? and therefore also the difference between matter? then everything that exists is built for the most part by the absence of matter?
