If the atoms in a material have a three dimensional preferred bonding pattern, at the surface some of those bonds are unsatisfied.

Sometimes a molecule will segregate to a surface or interface. Usually these surface enriched molecules are pushed out of the bulk (thermodynamically - no maxwell's demons here!). In this case, the molecules at the surface are usually different from the ones in the bulk interior. Since something has to go to the surface, thermodynamics favors keeping the best conditions for the majority of molecules in the bulk, and the less common chemistries are enriched at the surface. <...
