Surface tension; Gibbs adsorption; solvation; electrolyte; water clusters; polarization

We study a simple model of ionic solvation inside a water cluster. The cluster is modeled as a spherical dielectric continuum. It is found that unpolarizable ions always prefer the bulk solvation. On the other hand, for polarizable ions, there exists a critical value of polarization above which surface solvation becomes energetically favorablefor large enough water clusters.
