Misleading on Griffith electrodynamix(electric dipole)

In the books of electrodynamics by Griffith, He explain the physical view of the polarization inside of the dielectric matter. He try to make a picture polarized charge being offset near one.
However, I wonder how the chage can be offset with other molecular but not with own proton. Definitely, distance between the eletron and proton is near than moleculars.
How could it happen?

Figure 4.11: a row of plus and minus signs along a line, with plus signs at the right end and minus signs at the left, showing a bar electret's aligned dipoles; the central cancelled charges are circled in red.

Textbook page on electric fields in matter showing a table of atomic polarizabilities for elements H through Cs, and two sphere diagrams: a positive nucleus inside a negative electron cloud (Figure 4.1) and the displaced nucleus under field E (Figure 4.2).

There is no offset. As you see in the picture, there is negative charge at the left end, positive at the right end, and zero charge along the rest of the line in between.
