The diffusion and viscosity coefficients of liquid Mg, Ca, Sr and Ba were calculated by using scaling laws which expressed the possible relationships between the excess entropy and transport properties of liquids. The excess entropies were calculated by means of the 2-body approximation. The version of the electron-ion potential which had been proposed by Fioalhais and others, originally for the solid state, was used as the input pseudopotential. Static structure-factors were derived from the solution of the Ornstein-Zernike integral equation, with Rogers-Young closure. The present investigations showed that these scaling laws led to good estimates of the diffusion and viscosity coefficients of liquid alkaline-earth metals.
