Electronegativity Electron affinity

All the elements in a main group have in common a characteristic valence electron configuration. The electron configuration controls the valence of the element (the number of bonds that it can form) and affects its chemical and physical properties. Five atomic properties are principally responsible for the characteristic properties of each element atomic radius, ionization energy, electron affinity, electronegativity, and polarizability. All five properties are related to trends in the effective nuclear charge experienced by the valence electrons and their distance from the nucleus. [Pg.702]

In the next section we shall recall the definitions of the chemical concepts relevant to this paper in the framework of DFT. In Section 3 we briefly review Strutinsky s averaging procedure and its formulation in the extended Kohn-Sham (EKS) scheme. The following section is devoted to the presentation and discussion of our results for the residual, shell-structure part of the ionization potential, electron affinity, electronegativity, and chemical hardness for the series of atoms from B to Ca. The last section will present some conclusions. [Pg.161]

M It should be noted that inasmuch as the ionization energy of most atoms is an order of magnitude larger than the electron affinity, electronegativity methods which are fundamentally related only lo ionization energies are still successful. [Pg.644]

In this section we discuss the various atomic properties that are the manifestation of the electronic configurations of the atoms discussed in the previous sections. These properties include ionization energy, electron affinity, electronegativity, etc. Other properties such as atomic and ionic radii will be discussed in subsequent chapters, as these properties are related to the interaction between atoms in a molecule. Toward the end of this section, we will also discuss the influence of relativistic effects on the properties of elements. [Pg.64]

Germanium is disposed in the center of group 14 of the periodic table of the elements. Increased stability of divalent species, which is more pronounced for tin and lead, begins from this element. The main characteristics of these atoms, such as atomic radius, energy of ionization, electron affinity, electronegativity and other features, are presented in parallel in a review12. [Pg.1487]

In basic research, the chemistry of gold and organogold compounds merits special interest because of the unique position of gold in the periodic table, which is characterized by the highest electron affinity, electronegativity, and redox potential of all metals. These properties have their origin in a pronounced maximum in the relativistic contraction of the valence electron orbitals and associated effects. Several reviews on organogold chemistry have been published. ... [Pg.1464]
