The Topological Index mF of Electronegativity and Its Calculation of Physical and Chemical Properties of Inorganic Compounds

Enlightened by the topological index mX of the Randic molecular connection, the author formed the topological index mF of electro negativity. Utilizing the zero and first order indexes of mF related with 20 kinds of alkali halide consisting of lattice energy, enthalpy of formation and hydrated energy, 51 kinds of ion hydrated heat and 80 kinds of ion standard heat of formation, the several regression equations were suggested. Their related coefficients (indexes) are 0.9954 (0.9954), 0.9835 (0.9840), 0.9794(0.9795), 0.9948 and 0.9865, which meet the good or excellent standards. The structure selectivity achieves its only expression. Hence the calculation gains satisfactory results.
