Covalent Bonds

Structure and Bonding covers introductory atomic and molecular theory as given in first and second year undergraduate courses at university level. This book explains in non-mathematical terms where possible, the factors that govern covalent bond formation, the lengths and strengths of bonds and molecular shapes. Throughout the book, theoretical concepts and experimental evidence are integrated. An introductory chapter summarizes the principles on which the Periodic Table is established, and describes the periodicity of various atomic properties which are relevant to chemical bonding. Symmetry and group theory are introduced to serve as the basis of all molecular orbital treatments of molecules. This basis is then applied to a variety of covalent molecules with discussions of bond lengths and angles and hence molecular shapes. Extensive comparisons of valence bond theory and VSEPR theory with molecular orbital theory are included. Metallic bonding is related to electrical conduction and semi-conduction. The energetics of ionic bond formation and the transition from ionic to covalent bonding is also covered.

This comprehensive and innovative text provides an understanding of the geometric and electronic structure of surfaces. It addresses the surfaces of covalent and ionic solids and also metals. The book emphasizes fundamental aspects, such as the principles of surface crystallography and thermodynamics, the forces driving the rearrangement of the atoms, and the relationship between bonding and electronic structure. The book illuminates the relationship between surface orientation, chemistry, energetics, and the resulting properties. The text includes a discussion of elementary excitations at surfaces, their description and measurement. The general physical arguments and methods presented in the book will also allow the reader to analyse novel surfaces and interfaces of new materials. This makes the book an indispensable reference to all those studying growth, surface-molecule interactions, self-assembled structures, property engineering and materials development.

Phosphodiester bonds - A phosphodiester bond is a group of strong covalent bonds between the phosphorus atom in a phosphate group and two other molecules over two ester bonds. Phosphodiester bonds are central to all life on Earth, as they make up the backbone of the strands of DNA.

Noncovalent bonding - Noncovalent bonding refers to a variety of interactions, that are not covalent in nature, between molecules or parts of molecules that provide force to hold the molecules or parts of molecules together usually in a specific orientation or conformation. These non-covalent interactions include: ionic bonds, hydrophobic interactions, hydrogen bonds, Van der Waals forces (aka London dispersion forces), Dipole-dipole bonds.

Van Arkel-Ketelaar triangle - Bond triangles or Van Arkel-Ketelaar triangles are triangles used to show different compounds in varying degrees of ionic, metallic and covalent bonding. The bond triangle shows that ionic, metallic and covalent bonds are not just particular bonds of a specific type.

Electron deficient - A compound that is electron deficient has too few valence electrons for the connections between atoms to be described as covalent bonds. Electron deficient bonds are often better described as 3-center-2-electron bonds.
