WebMay 22, 2024 · What is Electronegativity – Pauling Scale – Definition. Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used. The electronegativity of fluorine … WebElectronegativity was developed by Linus Pauling, who won the Noble prize twice. Pauling set the definition of electronegativity as “the power of an atom in a molecule to attract electrons to itself”. He did not come up with the concept, which was introduced by Jöns Jacob Berzelius in 1811, but he did develop a measurable scale, circa 1935.
