Fluorine effect atom electronic configuration

The effects of the fluorine atom s special electronic configuration in organic molecules arise from its unique combination of properties ... 

The augmented correlation consistent basis sets, when combined with coupled cluster or multireference configuration interaction methods, have been found to provide an accurate description of atomic electron affinities. The calculated EAs of boron and fluorine are summarized in Table 26 and the basis set convergence errors are plotted in Figure 13. The values of the EAs of these two atoms, 6.39 0.23 kcal mol (B) and 78.82 kcal mol" (F), respectively (corrected for spin-orbit effects), bracket the EAs of the other first-row atoms. 

Ans. Magnesium, atomic number 12, can achieve the Ne configuration, atomic number 10, by the loss of two electrons. Fluorine requires only one electron to achieve the Ne configuration. This transfer can be effected if two fluorine atoms react with one magnesium atom ...
