What is the difference?

When I say perfectly round/flat, I mean as round or flat as atoms can get. I understand that because of the electron cloud, the round or flat part can never be the same.

As close as possible. I'm not very knowledgeable of physics, so feel free to explain.

Theoretically, if you had a perfect circle, and a perfectly flat surface, wouldn't only one atom touch at a time (assuming friction can't take away the perfect circle/flat surface)? Personally this doesn't sound right, but I can't think of why it wouldn't.
