The atoms are vibrating in place.
A crystalline solid (like salt, NaCl) has atoms/ions arranged in a regular repeating lattice. In that solid state the particles stay at fixed lattice positions and only vibrate about those positions (they do not slide past each other or spread out, and they are not arranged randomly).
