That's if you assume that electrons and nuclei are solid objects.
In reality they are ripples in fields which completely fill the space
they occupy (and quite a bit of the space around the atoms).
³I want to emphasize that light comes in this form‹particles. It is

something about light behaving like waves. IŒm telling you the way it

Theory of Light and Matter." (Emphasis his.)
The trouble with that is that even things we think of as particles can
behave as waves when it suits them (when the experiment asks the right
question). Wave particle duality describes this odd behaviour.
Quantum mechanics is strange - things behave like a wave to decide where
to go (approximately along the path of least time) and then like a
particle when they get there to deliver a quantum of energy.
Electrons, silver atoms and even buckeyballs will obey diffraction in
the Young's slit experiment once you make the slits small enough. They
have pushed the size up a bit since I last looked too:

They can show diffraction of molecules up to about 10000 amu now.
