An element’s electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity (χ ≥ 2.2 in Figure 2.12.2) have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i.e., they are oxidants ).
Simple linear relationships exist between the above two quantities, which divide metals into four groups, roughly: sp, transition, alkali and alkali earth metals. The difference between the electronegativity for atoms in An element’s electronegativity provides us with a single value that we can use to characterize the chemistry of an element. Elements with a high electronegativity (χ ≥ 2.2 in Figure 2.12.2) have very negative affinities and large ionization potentials, so they are generally nonmetals and electrical insulators that tend to gain electrons in chemical reactions (i.e., they are oxidants ).
The unity used for the electronegativity is Pauling. Please note that the elements do not show their natural relation towards each other as in the Periodic system. There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. 1,17: Gadolinium
Pauling established Electronegativity as the "power" of an atom in a molecule to attract electron to itself. It is a measure of the atom's ability to attract electron to itself while the electron is still attached to another atom. The higher the values, the more likely that atom can pull electron from another atom and into Chemical elements listed by electronegativity The elements of the periodic table sorted by electronegativity.

The most electronegative element is fluorine. The least electronegative or most electropositive element is francium. The greater the difference between atom electronegativity values, the more polar the chemical bond formed between them. The unity used for the electronegativity is Pauling. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
Electronegativity is a measure of the ability of an atom to attract the electrons when the atom is part of a compound. Electronegativity values generally increase from left to right across the periodic table. Electronegativities generally decrease from top to bottom of a group.

An atom’s electronegativity in a molecule is related to its energy of ionization and its affinity with electrons, which are properties of isolated atoms. Its depends on the structure of the atom and the number and kind of atoms with which it may combine.
If you were only considering elements, then yes, fluorine would be the most electron withdrawing of all the eleme Pauling’s electronegativity scale was originally defined for atoms and as such is limited in its applicability to problems concerning organic structures. As a consequence, it was used as the basis of other concepts, such as bond electronegativity, orbital electronegativity, and group electronegativity. For Since electronegativity increases across a period, electropositivity decreases across periods.
