Expert Answer:

The p and n sides are both neutral. In the n side there are fixed cores of acceptors  with effective positive charge and associated extra electrons. Note that these charges add up to zero.

The electrons leave the material, but the cores are fixed and don't move, so the ionized donar atom is left behind.
