Linus Pauling described electronegativity as “the power of an atom in a molecule to attract electrons to itself.” 1 Basically, the electronegativity of an atom is a relative value of that atom's ability to attract election density toward itself when it bonds to another atom.

The Pauling Electronegativity Scale. The original electronegativity scale, developed in the 1930s by Linus Pauling (1901– 1994) was based on measurements of the strengths of covalent bonds between different elements.
Linus Pauling described electronegativity as “the power of an atom in a molecule to attract electrons to itself.” 1 Basically, the electronegativity of an atom is a relative value of that atom's ability to attract election density toward itself when it bonds to another atom.
Figure 6.2.2 shows the electronegativity values of the elements as proposed by one of the most famous chemists of the twentieth century: Linus Pauling (Figure 6.2.3). In general, electronegativity increases from left to right across a period in the periodic table and decreases down a group.
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.
About. Transcript. A covalent bond involves the sharing of electrons between two atoms, but they typically are not shared equally. The difference in electronegativity between the two atoms defines whether a bond is classified as nonpolar covalent or polar covalent. Created by Sal Khan. Questions. Tips & Thanks.

Apr 7, 2021 · Pauling’s electronegativity scale has a fundamental value and uses accessible thermochemical data, but fails at predicting the bonding behavior for several elements.
