Electronegativity. Pauling definedelectronegativity is the power of an atom in a molecule to attract the shared pair of electrons. It is one of the most widely used scales of electronegativity. According to Paulingelectronegativity scale, Fluorine has more ability to attract electrons to itself, followed by oxygen.

Electronegativity. Pauling definedelectronegativity is the power of an atom in a molecule to attract the shared pair of electrons. It is one of the most widely used scales of electronegativity. According to Paulingelectronegativity scale, Fluorine has more ability to attract electrons to itself, followed by oxygen.Electronegativity , symbol χ , is a chemical property that describes the tendency of an
atom to attract a shared pair of electrons (or
electron density ) towards itself. [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 associated electronegativity number, the more an element or compound attracts electrons towards it.
The term "electronegativity" was introduced by
Jöns Jacob Berzelius in 1811, [2] though the concept was known even before that and was studied by many chemists including
Avogadro . [2] In spite of its long history, an accurate scale of electronegativity was not developed until 1932, when Linus Pauling proposed an electronegativity scale, which depends on bond energies, as a development of valence bond theory . [3] 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
