From the energy band approximation of K RONIG and P ENNEY and T AMM'S model of surface states a contribution of the electrons localized at the surface to the surface tension of a solid has been deduced. The results illustrate the difference between the surface tension and the surface energy in the case of a solid. It has been explained how the above mentioned contribution to the surface tension is connected with the existence of a surplus surface‐near lokal stress.
