Abstract: Conditions of unstable equilibrium of single-layer islands of the adsorbate and empty adsorption vacancies are studied. An analog of the Kelvin–Thomson effect for these islands is found. Appropriate corrections are made in the classical theory of nucleation.

Keywords: Langmuir sorption model, surface diffusion, nucleation, Kelvin–Thomson effect, condensation.
