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.
It is to be expected that the electronegativity of an element will vary with its chemical environment, [7] but it is usually considered to be a transferable property, that is to say that similar values will be valid in a variety of situations. Caesium is the least electronegative element (0.79); fluorine is the most (3.98).
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
Fluorine is the most reactive of all elements; it is the only element more electronegative than oxygen, it attacks otherwise-inert materials such as glass, and it forms compounds with the usually inert noble gases. It is a corrosive and highly toxic gas.
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.
Fluorine is very difficult to form oxoacids with, due to the fact that it will take a lot of energy per mole to join each additional oxygen atom to fluorine owing to its exceptional electronegativity. The only known oxoacid of fluorine is hypofluorous acid (HOF). It appears as a white-solid below temperatures of -117°C, and a pale-yellow ...
This results in an ionization energy low enough to form stable compounds with the most electronegative elements, fluorine and oxygen, and even with less electronegative elements such as nitrogen and carbon under certain circumstances. [1] [2]
Xenon can be directly bonded to a less electronegative element than fluorine or oxygen, particularly carbon. [22] Electron-withdrawing groups, such as groups with fluorine substitution, are necessary to stabilize these compounds. [16] Numerous such compounds have been characterized, including: [17] [23] C 6 F 5 –Xe + –N≡C–CH
