In terms of an interatomic pair potential, possessing a soft repulsive core and the long-range Friedel oscillations, we have recently reproduced the anomalous structures and dynamic properties of liquid Ga just above the melting point. In this paper, evaluating separately for the model and the corresponding repulsive core by numerical simulation and the hard-sphere perturbation theory, we investigate the contribution due to the Friedel oscillations to the excess entropy of the model fluid. For the two model fluids, the density variations of the pair-correlation and residual-multiparticle entropies are also presented.
