The Planck unit of length is about 10-35 meters, whereas the diameter of an atom is of the order of 10-8 meters. This means that in an average atom there would be 10-35/10-8 Planck lengths which is 10-27 Planck lengths or:

10000000000000000000000000000 Planck lengths.

Quantum foam doesn't have any effect on the vacuum until you get down around the scale of the Planck length. Do you now understand why your answer is so ridiculous?

See Hardy's response for the correct answer.
