Abstract: The viscosity of liquid metals is investigated in a wide temperature range using the model potential of interatomic interaction. The periodic dependence of the coefficient of viscosity on the element atomic number is treated, and the correlation between the viscosity and effective valency is determined. It is demonstrated that the hard-sphere model with the packing density $\eta_m=0.48$ at the melting temperature reproduces well the viscosity of melts in which the metallic bond predominates.
