Chemical bonding - Atomic Structure, Intermolecular Forces, Covalent Bonds: To understand bond formation, it is necessary to know the general features of the electronic structure of atoms—that is, the arrangement of electrons around the central nucleus.
This chapter discusses atomic structure and chemical bonding. The wave-mechanical treatment of the hydrogen atom leads to a definition of a series of electronic energy levels or orbitals that a single electron can occupy. The orbitals are grouped into shells and are designated by a principal ...

The purpose of this work was to study and elucidate the nature of the chemical bond in the atomic structure of substances in order to establish the fundamental laws of natural science. It is assumed that in the course of evolution of the Universe during collisions of oppositely charged ...

The structures were refined isotropically using soft restraints for the geometry of the phenyl rings as well as the C–C and C=N bond lengths. The observed peaks appeared to be spherical with similar peak heights for the same atom types. The porous structure of E-FCOF-5 (f-up) and C-...
This figure also indicates that the QMo alloy was heated into the supercooled liquid region during the first heating and major changes to the atomic structure occurred, as can be seen from the substantial irreversible shift of the diffraction peak positions after the initial heating. However, the ...

Based on the knowledge of APBs, some strategies are proposed and applied to design APBs artificially in magnetic oxide materials, where these APBs have an intriguing antipolar structure phase19. Many studies have focused on and designed APB-related chemical and physical properties20,21, but the ...
