Electronegativity selected elements

TABLE 3.2 Electronegativity of selected elements according to Pauling. 

Table I. Electronegativities of Selected Elements and Ionic Character and Ionic Bond Energies of Si-X Bonds...

Pauling electronegativity values (x ) for selected elements of the periodic table... 

Electronegativity values for selected elements. Note that metals have relatively low electronegativity values and that nonmetals have relatively high values. 

Ans. Not generally. For example, for carbon to form an ion to aehieve noble gas configuration, it must lose or gain four electrons. The electrical work to accomplish that is very large, and almost never available in ordinary chemical reactions. In those cases where the necessary electrical work to remove electrons from the valence shell is not available, electrons will be shared in a covalent bond. In Sec. 3.4 we will discuss a concept related to electron affinity, called electronegativity, which offers a quantitative method for deciding whether or not an ionic bond will form in the reaction between two selected elements. 

TABLE 5.12 Electronegativities of selected elements using the revised Pauling scale, the Mulliken-Jaffe scale, and Allen s spectroscopic configuration energies. The iatter scales have been converted to the revised Pauling scale. The Mulliken-Jaffe values are listed for the sp valence hybridization, uniess otherwise indicated.
