Abstract A formula for surface energy, ω, in terms of electron work function, φ, and the effective number of free electrons per atom, z , is given. The basis for its derivation were the known equations of the free electron theory of metals and the known advanced Frenkel's relation between electron work function and heat of sublimation. Furthermore in the formula ( M atomic mass, γ density) \documentclass{article}\pagestyle{empty}\begin{document}$ \omega = \frac{{1530}}{q}\,\frac{\varphi }{{(M/\gamma)^{2/3} }}z^{2/3} $\end{document} details of the crystal structure of metals were taken into account by introducing the structural coefficient q. The calculated values of surface energy were compared with experimental data.
