Abstract

The concept of chemical hardness was originally developed as a measure of the stability of molecules. Its relationship to physical hardness and to solids is demonstrated here. Also, it is shown that shear moduli, and polarizabilitites, as well as band gaps are related to chemical hardness. Finally, evidence is presented that indentation hardness numbers are better measures of critical phase transition compressions than “pressure-cell” data.
