Definitions for electronegativity
This page provides all possible meanings and translations of the word electronegativity
(chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond
the tendency, or a measure of the ability, of an atom or molecule to attract electrons and thus form bonds
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom or a functional group to attract electrons towards itself. An atom's electronegativity is affected by both its atomic number and the distance that its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. First proposed by Linus Pauling in 1932 as a development of valence bond theory, it has been shown to correlate with a number of other chemical properties. Electronegativity cannot be directly measured and must be calculated from other atomic or molecular properties. Several methods of calculation have been proposed, and although there may be small differences in the numerical values of the electronegativity, all methods show the same periodic trends between elements. The most commonly used method of calculation is that originally proposed by Linus Pauling. This gives a dimensionless quantity, commonly referred to as the Pauling scale, on a relative scale running from around 0.7 to 3.98. When other methods of calculation are used, it is conventional to quote the results on a scale that covers the same range of numerical values: this is known as an electronegativity in Pauling units.
