The same fairway exists in these data on compressibilty of minerals - the least compressible oxides of hard cations fall in the same fairway from upper left to lower right. All of these properties of oxides follow the same pattern, seemingly in response to the issues of cation-oxygen bonding and cation-cation repulsion that we discussed earlier.

        You might wonder why I'm focusing on oxides, and I would answer that O2- is our most abundant anion and thus it makes the compounds of greatest interest. However, to be open-minded . . . .
