A functional-link net(FLN) was employed to correlate a set of atomic structural descriptors, such as electric charges ( Z), ionic radii ( r), electron numbers in the valence layer (f, d, s) , principal quantum numbers in the outer-shell ( n ) , electronegativity (xp ) , and the factor of adaptive valence orbit number(w) of the metal ions with known stable constants (logK) of ethylenediamine tetraacetic acia complexes of 60 metal ions.
The paper deals with the correlation between energy of valence orbit and doping MgB2 Superconductors. It is found that the average values of valence orbits parameters's average energy about cations and anions concentrate in 9.9ev to 10.3ev,and the difference of that concentrate is in 3.1ev to 4.4 ev for doping MgB2 Superconductors.
In this paper, an equation is given relating bond length of diatomic halide molecule with avergy energy of valence orbit and position of the elements constituting the diatomic molecule in the periodic table.
The diffence between the geometri averages of negative of energy of valence orbit for cations and anions in suggested conducting resonance elements of some cuprate high temperature superconductors with two layers of CuO 2 are evaluated. The relationship between ΔX 0 and crisis themperature T c was found to fit line.
The hybrid schemes of The valence orbit of central matter (atom or ion ) in co-ordination compound assume control of their co-ordination numbers and geometrical configuration of molecules, and one of the schemes, the a hybrid scheme, plays an important role.In this article, possible existence of a hybrid orbit corresponding to those elements in each block of the periodic table for central matter (atom or ion) in co-ordination compound has been analysed systematically with the help of group...
In this paper, an equation is given relating bond length of diatomic halide molecule with avergy energy of valence orbit and position of the elements constituting the diatomic molecule in the periodic table. The bond lengths of some common haloid molecules are calculated with the equation. The calculated results are in agreement with the experimental data.
In this paper ,a formula is given relating the bond length of diatomic halide molecule withthe average energy of valence orbit. The bond iengths of seventy-five common haloid molecules arecalculated with the formula. The calculated results are in agreement with the experimental data.
