== Physical factors that determine the work function ==

Due to the complications described in the modelling section below, it is difficult to theoretically predict the work function with accuracy. Various trends have, however, been identified. The work function tends to be smaller for metals with an open lattice,{{what|date=octoberOctober 2020|reason=open not defined}} and larger for metals in which the atoms are closely packed. It is somewhat higher on dense crystal faces than open crystal faces, also depending on [[surface reconstruction]]s for the given crystal face.
