Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1] An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the ...

Not surprisingly, S E gives the same ordering of the main group elements as the electronegativity, though it differs in its numerical value from traditional electronegativity scales. Because it is defined in structural terms, S E is the preferred measure of electronegativity in the bond valence model, [ 9 ]
The image shows a periodic table extract with the electronegativity values of metals. [12] Wulfsberg [13] distinguishes: very electropositive metals with electronegativity values below 1.4 electropositive metals with values between 1.4 and 1.9; and electronegative metals with values between 1.9 and 2.54.
Shape of water molecule showing that the real bond angle 104.5° deviates from the ideal sp 3 angle of 109.5°.. In chemistry, Bent's rule describes and explains the relationship between the orbital hybridization and the electronegativities of substituents.

A list of the electron affinities was used by Robert S. Mulliken to develop an electronegativity scale for atoms, equal to the average of the electrons affinity and ionization potential. [ 2 ] [ 3 ] Other theoretical concepts that use electron affinity include electronic chemical potential and chemical hardness .
