Ionocovalency model includes quantum parameters, sub-models and dual parameter groups,  we can calculate  all  electron configuration data from 1s to nf, from it:  

IC = n*(I_av /R)^½ r_c^-1

or in some cases by using the ultimate ionization energy I_z instead of I_av, we can get more valuable results:  

IC = n*(I_z /R)^½ r_c^-1 

and we can explain almost all chemical phenomena from IC model:

  IC (I_z , r_c , n*, I_av , r_c^-1, n*r_c^-1, Z*) = I ( I_z )C(n*r_c^-1) = n*(I_av/R)^½ r_c^-1

 where

Ultimate ionization energy: I_z,   from spectroscopy

Covalent radius: r_c,   from X-ray diffraction

Effective principal quantum number:

n* = n* 0.85, 1.99, 2.89, 3.45, 3.85, 4.36, 4.99.

Ionicity: I_av= n^-1∑ⁿ_i=1 I_i

Covalency: r_c^-1

Special covalency: n*r_c^-1

Effective nuclear charge: Z* = n*( I_z /R)^½

IC-potential:   n*(I_av/R)^½ r_c^-1

IC model: I ( I_z )C(n*r_c^-1) = n*(I_av/R)^½ r_c^-1

Dual Method:

IC (I_z , r_c , n*, I_av , r_c^-1, n*r_c^-1, Z*) = I ( I_z )C(n*r_c^-1) = n*(I_av/R)^½ r_c^-1
