摘要：
In this paper we have theoretically predicted the physical parameters viz, coordination number, constraints, molar volume, fraction of floppy modes, number of lone pair electrons, glass transition temperature, bond energy, cohesive energy, heat of atomization, mean bond energy and viscosity for (Se80Te20)(100-x)Ag-x. (0<x<4) glassy alloys. It has been found that average number of constraints, cohesive energy and mean bond energy increases with the increase in Ag content. The mean bond energy is calculated using the chemical bond approach of Tichy and Ticha and it was found that the mean bond energy and number of lone pair electrons of the system decrease with increase in Ag content.
