A photon, at least a visible one never hits a nucleus.
A nucleus is in the order of 1 fm, while an Atom is in
the order of 1Angstrom, (100 pm). So a visible photon
with a wavelength in the region of 1um also never hits
an atom. For some reason the valence electrons in an
atom can pick a visible photon up.
