Static structure factors, S(q), thermodynamic properties and shear viscosit
ies for liquid Zn, Cd, Hg, In, Tl, Sn, Pb, Sb, and Bi are investigated syst
ematically. A model pseudotential which combines the sp- and d-band contrib
utions is employed to derive interionic interactions. The liquid state is d
escribed by using the thermodynamically self-consistent variational modifie
d hypernetted chain (VMHNC) integral equation theory, and also by using the
linearised version of the Weeks-Chandler-Andersen (LWCA) thermodynamic per
turbation theory of liquids. Results of calculations for all of the above p
roperties are found to be in good agreement with available experimental dat
a. The calculated results also reveal qualitatively that there is a relatio
nship between the rate of change of viscosity with temperature and the dept
h of the potential well concerned.
