If an atom is 99.99% empty space, what percent empty space is the same atom in a black hole?

Basically I want to know how much closer the nucleus and electrons are when in a black hole.

Black holes lack any kind of atomic structure, or any kind of internal structure at all.

They're effectively a region of space which acts like a fundamental particle, retaining only mass, spin, and charge.
