The atomic diffusion in liquid Na, K, Cs, Mg, Al, In and Pb have been evaluated from the well-known Einstein’s formula of self-diffusion coefficient, D  D  kBT ⎞ under square well (SW) interaction. The friction coefficient, ( of liquid    ⎝ ⎠ metals has been computed on the basis of Helfand-Rice-Nachtrieb approach under Helfand’s linear trajectory (LT) approximation. Shear viscosity of liquid metals were determined using modified Stokes-Einstein equation for SW potential. Dzugutov’s scaling was modified for SW interaction and has been employed to compute excess entropy of the considered liquids. The isothermal compressibility of liquid metals was determined using equation of state of SW potential. Surface entropy of these liquids has been determined through temperature derivative of surface tension. Dzugutov’s scaling law has also been tested in these liquid metals. It is found that the various transport and surface properties of these liquid metals extracted from the diffusion coefficients are in a good agreement with the experimental data.
