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 connection comes from the Mulliken electronegativity scale. By inserting the energetic definitions of the ionization potential and electron affinity into the Mulliken electronegativity, it is seen that the Mulliken chemical potential is a finite difference approximation of the electronic energy with respect to the number of electrons, i.e.,

The tendency of an atom in a molecule to attract the shared pair of electrons towards itself is known as electronegativity. It is a dimensionless quantity because it is only a tendency. [17] The most commonly used scale to measure electronegativity was designed by Linus Pauling. The scale has been named the Pauling scale in his honour.
California will have the highest minimum wage rate for any state at $15.50, up from $15 in 2022. It raised its minimum wage to $14 in 2021 from $13, the result of a law mandating incremental ...
The Wisconsin Department of Public Instruction's 2023-24 state report card data revealed that 84% of Wisconsin's schools have met, exceeded or significantly exceeded expectations.
It also has a high electron affinity, second only to chlorine, [17] and tends to capture an electron to become isoelectronic with the noble gas neon; [3] it has the highest electronegativity of any reactive element. [18] Fluorine atoms have a small covalent radius of around 60 picometers, similar to those of its period neighbors oxygen and neon.
