App lication o f the GM A equation of stat e to predict the metal-non metal transitio n

The metal-non-metal transition occur s when the dense liquid is expanded t o lower densitie s.The dense liquidis a metallic conductor in which t he interparticle interac tionsare dominated by the coulomb potential, whereas the interactions in the non-metallic phase are weak v an der Waals forces.Both types of interactions change with the thermo dynamic state.Liquid metals such as mercury, rubidium, and cesium areelectric ally conductive at normal conditions. They beco me nonmetallicwhen expanded to lower densities. The density of ane lement may be regarded as the main criteria for its metallic o r non-metalli ccharacteristic.
