Discussion of Atomic Radii Based Periodicities

The above discussed response indices of an atomic electronic system to the environment influence can be directly particularized once an atomic radii scale is available. However, here we will focus on the present S-DFT 

TABLE 4.17 For the First Four Periods Of Elements, Using the DFT Atomic Radii (Second Colurrm), There Are Displayed the Calculated Diamagnetic Susceptibility, Static Dipole Polarizability, the Softness and Electronegativity Related Chemical Elardness and the Experimental First Ionization Potentials, From the Left to the Right Colunms, Respectively (Putz et ah, 2003, 2012b,c)

The values in the Table 4.17 are relatively to the used formulas in terms of the atomic radii scale that is considered. There are also relatively to Ihe assumed approach to replace all average dependencies with the atomic radii dependencies so that all the iimer structure properties for an atomic system was concentrated its outer shell properties. This is naturally justified is looking to the global atomic response to the external influences where the outermost electrons are the mainly involved.
