2. ATOMIC RADII AND SCALES AND ELECTRONE... > 2. ATOMIC RADII AND SCALES AND ELECT... - Pg. 122

Nanoroots of Quantum Chemistry by another atomic radii related information. This should be electronegativity, as a unique value (be- cause the equalization of orbital electronegativities in atoms), to be involved as the missing informa- tion. To arive at the electronegativity is simply to consider the competition between Ghosh-Biswas condition and the suplemented one: STO ( x ) x = R linear regressions of STO atomic radii in terms of electronic atomic charge. We get the following relationships (Putz, 2004): Boyd R < 3 > - Markus - STO = 0 . 653473 + 0 . 0116798 Z R Ghanty - Ghosh - STO = 1 . 11907 + 0 . 0323337 Z < 5 > Mulliken R < 7 > - Putz - STO = 0 . 739578 + 0 . 0116477 Z = 0 at the atomic radii fronter. In the case that we perform the ratio betwen the two above condi- tions to get a more comprehensible atomic radii determination, as a parameter at which both gradient of density as well as the density itself vanish (immediately near, for increasing sense, of the atomic radii). The inderetminate raport, R Ghosh - Biswas = 1 . 03772 + 0 . 0300192 Z < 8 > which are represented toghether in the lower part of Figure 10. It is clear also from the linear representation that equations Ghanty-Ghosh, with numerical values in collum <5>, and Ghosh- Biswas with collum <8> as particularization, belongs to the same class of atomic radii scales,
