Scales of electronegativity, chi, can be evaluated against an empirical relationship between bond character and chi. A data set of binary compounds whose bond types were specified as metallic, covalent, or ionic was used to evaluate 15 scales. For each scale, plots of differences in chi, Delta chi, vs average chi, chi were made for all compounds of specified bond type. These 2-D plots produce triangular graphs that exhibit tripartite separation of the three bond types which show increasing covalency along one axis and increasing ionicity along the other axis. All but one scale produce graphs that give segregation of compounds by metallic, covalent, and ionic bond type of better than 87% for all comopunds with chi’s defined by that scale. Two scales, those of Alien and of Nagle, provide better than 96% separation into the three bond type regions.
