The aim of this paper is to review the actual data on the chemical bond in binary and mixed oxides. The electronegativity (χM) and the acidity pa scales are the most significant semi-empirical concepts for predictingthe trend of bonding character in iono-covalent oxides. A satisfactory correlation between the data issued from the acidity scale and the calculated ionic charges has been established
