A comparative study of the atomic transport properties of liquid alkaline metals using scaling laws

Certain atomic transport and surface properties of liquid alkali metals are reported. Using scaling laws proposed by Rosenfeld, Dzugutov and Li and coworkers, which express the possible relationship between the excess entropy and transport properties of liquids, the diffusion and viscosity coefficient of liquid Na, K, Rb and Cs metals are calculated. The excess entropies are computed by two-body approximation. The pair distribution functions are calculated from the solution of Ornstein–Zernike integral equation with Percus–Yevick closure using the individual version of the electron-ion potential proposed by Fioalhais and coworkers which was originally developed for solid state. Simulation results give sound support to these scaling laws.
