The chemical behavior of a substance is mainly governed by its degree of acidity or alkalinity. The so-called proton affinity plays a role as a decisive factor and shows how easily an entity emits or attracts a single proton.

The measurement of the proton affinity of molecules has been relatively easy than it is for surfaces. This is crucial because atoms on surfaces exhibit extremely different proton affinities, based on where they are located.
