We present a quantum mechanical model capable of describing isotropic compression of single atoms in a non-reactive neon-like environment. Studies of 93 atoms predict drastic changes to ground-state electronic configurations and electronegativity in the pressure range of 0–300 GPa. This extension of atomic reference data assists in the working of chemical intuition at extreme pressure and

Electronegativity. 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. The electronegativity of Argon is: χ = — Electronegativity = 0.5 x (Electron Affinity + Ionization Potential) Group Electronegativity. In Organic chemistry, it associates with many functional groups rather than with the individual atoms. However, it is very normal to differentiate between the resonance effect and the inductive effect.

Electronegativity increases left to right across a row in the periodic table e.g. C < N < O < F (as you move left to right nuclear charge increases so there is a greater attraction for electrons) ; Electronegativity decreases as you move down a group in the periodic table e.g. F > Cl > Br > I (each step down a group increases the atomic radii as a "new shell" of electrons are added and the

Molecules are collections of atoms that are associated with one another through bonds. It is reasonable to expect — and the case empirically — that different atoms will exhibit different physical properties, including abilities to interact with other atoms. thus increasing the electronegativity of the atom. Pitzer pointed out the periodic behavior in the two atomic properties long ago30 and many others have relied on different de nitions of atomic radii (usually covalent radii) and electrostatic relation-ships to de ne scales of electronegativity.24,31–44 Electronegativity decreases as you move down a group in the periodic table e.g.

Across a period from left to right the electronegativity of atoms increases. As you move from left to right Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is given a value of 4.0, and values range down to caesium and francium which are the least electronegative at 0.7. Electronegativity means the tendency to attract the bond pair electrons towards it. There is actually no means of measurement of electronegativity, but still scientists like Pauling did compare electronegativity of others to oxygen and based on th Electronegativity is a property of atoms within molecules rather than free atoms. It measures the tendency of that atom to draw bonding electrons towards itself.
