Pauling electronegativity values 5-block elements

Table 4.7. Natural electronegativity values Xm(N) ( Pauling units ) for d-block (group 3-11) elements of the first three transition series (Sanderson values19 xfs> for the first transition series are given in parentheses)...

Electronegativities, Xp. shown in bold text and rounded to one decimal place, are taken from Allred or from Pauling. The values are based on thermochemical data analysed using Pauling s approach for the elements in their normal oxidation state, viz. for Sc, Y and La, M for Cu. Ag and Au, for the other d-block metals, Ln for the lanthanides and An for the actinides. 

The experimental work functions of the metals are related to the Mulliken electronegativities by a constant displacement, P = —0.9, —0.5, 0, 0.2, and 0.5 eV, for the majority of the elements. The Pauling and Allen Rochow electronegativities have systematic variations similar to the Mulliken electronegativities for the main group of elements, but the values are different in magnitude for the d and f block elements. 

Table 1.7 Pauling electronegativity (x ) values for the i - and / -block elements.

Fig. 1.24 Although electronegativity values for a given element from different scales cannot be expected to be the same, trends in values along a series of elements are comparable. This is illustrated with scaled values of x (Pauling red), x (Mulliken green) and x (Allred-Rochow blue) for first row elements from the p-block.
