it's certainly less mass-ive by a factor of a 1000 or so but then it's smeared across a volume, because quantum physics. in some sense, the concept of an atom and the electron 'space' are interchangeable if you think of those cute STM images of atoms spelling out words. this is one of those funny questions that go through a local maximum somewhere between ignorance and grad school. it's obvious right up until someone points out it's all really @#$@#$@ confusing.
