Electronegativity is not a uniquely defined property and may depend on the definition. The suggested values are all taken from WebElements as a consistent set. Many of the highly radioactive elements have values that must be predictions or extrapolations, but are unfortunately not marked as such.

Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [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 ...
This is the energy per mole necessary to remove electrons from gaseous atoms or atomic ions. The first molar ionization energy applies to the neutral atoms. The second, third, etc., molar ionization energy applies to the further removal of an electron from a singly, doubly, etc., charged ion.
The caveat originates from the simplifying use of electronegativity instead of the MO-based electron allegiance to decide the ionic sign. [6] One early example is the O 2 S−RhCl(CO)(PPh 3) 2 complex [13] with sulfur dioxide (SO 2) as the reversibly-bonded acceptor ligand (released upon heating
Chlorine (symbol Cl) is the second-lightest halogen. The element forms diatomic molecules under standard conditions , called dichlorine. It has the highest electron affinity and the one of highest electronegativity of all the elements; thus chlorine is a strong oxidizing agent .

First, as the energy that is released by adding an electron to an isolated gaseous atom. The second (reverse) definition is that electron affinity is the energy required to remove an electron from a singly charged gaseous negative ion. The latter can be regarded as the ionization energy of the –1 ion or the zeroth ionization energy. [1]
