Abstract: The atomic net charges of various halide molecules were calculated by Hartree-Fock SCF method. The values calculated correlate well with the liquid phase ionic conductance and some other physical properties of simple halides. These regularities are similar to those found in the bond-parametric diagrams we previously reported. The partial covalency of flourides, which can be explained by the stronger π bond formation, cannot be weakened by the antibonding involving inner p orbitals.
