The current chemistry of the Group IV elements has been reviewed in the second volume of the MTP series. In an analysis of the i.r. band intensities of a number of MHCI3 and MX4 (M = C, Si, or Ge X = F, Cl, Br, or I) molecules, the electronegativities of the Group IV elements have been shown not to vary smoothly as deduced by Pauling, but to vary erratically, as indicated by the Allred-Rochow and Sanderson Electronegativity scales (Table 1). 

On the basis of this equation, systematically considering all the available thermochemical data and arbitrarily assigning to the most electronegative element, fluorine, a value of about 4, Pauling was able to prepare a complete electronegativity scale. This is shown in Table 2.1. 

Mulliken has arrived at an electronegativity scale by another and better way, obtaining good agreement with that of Pauling (Table 15). 

Electronegativities of the elements are expressed on a somewhat arbitrary scale, called the Pauling scale (Table 6-3). The electronegativity of fluorine (4.0) is higher than that of any other element. This tells us that when fluorine is chemically bonded to other elements.
