The neighborship properties of several monatomic liquids are investigated. This builds upon indirect methods (numerical techniques) explored in experiments with 2D foams (Graham et al., J. Phys. Chem. B 1997, 101, 11211). In the foundation study, the methods were applied to the radial distribution function G(r) for foams and liquid sodium. Further development is presented here so as to widen the method applicability and to learn more about neighborship distributions. The method is demonstrated using G(r) for hard spheres; favorable comparisons are found between the distributions so obtained and via the theory of Mazur (J. Chem. Phys. 1992, 97, 9276). Using published G(r) data, application is made to a diverse set of monatomics: lithium, potassium, argon, indium, gallium, and mercury. Overall, this research offers structure comparisons among different liquids and identifies neighborship trends. In addition, a simple way to partition G(r) is further established which requires no specification of the interaction potentials.
