AbstractsBased on the Bohr quantum energy levels, a spectroscopic quantum model for easily calculating the effective nuclear charge Z* and the effective principal quantum number n* from the ionization energy Iz of the all orbitals from 1s to nf is established:

Z*=n*(Iz /R)½

No longer using the traditional rules for estimating artificially the shielding effects, the model successfully derived many important quantitative methodssuch as the IC-model, electronegativity, Lewis acid strengths, crosslink density and effective Polarizing Power, which can calculate and describe quantitatively chemical phenomena and the dual observations of the ionic and the covalent of bond, correlated with chemical theorems and regulations and predicted chemical processes and products.
