Which is the first ionization energy of argon?
Electronegativity of Argon is —. 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. First Ionization Energy of Argon is 15.7596 eV.
