chemical bond

n.
Any of several forces, especially the ionic bond, covalent bond, and metallic bond, by which atoms or ions are bound in a molecule or crystal.

chemical bond

n
(Chemistry) a mutual attraction between two atoms resulting from a redistribution of their outer electrons. See also covalent bond, electrovalent bond, coordinate bond
ThesaurusAntonymsRelated WordsSynonymsLegend:
Noun1.chemical bond - an electrical force linking atoms
attraction, attractive force - the force by which one object attracts another
covalent bond - a chemical bond that involves sharing a pair of electrons between atoms in a molecule
cross-link, cross-linkage - a side bond that links two adjacent chains of atoms in a complex molecule

In addition, we performed Fourier Transform infrared (FTIR) reflectance measurements in the terahertz spectral range in order to get more information about the microstructure and basic chemical bonding of the studied compositions.
The high brightness/narrow energy spread of the next-generation Cold-FEG achieves high energy resolution electron energy loss spectroscopy (EELS) for rapid identification of chemical bonding states.
Dr Marcus Durrant realised that the treatment of hypervalency in the Lewis theory of chemical bonding was flawed while he was teaching the theory to students.
The first volume focuses on fundamental aspects of chemical bonding, and presents such perspectives as the physical origin of covalent bonding, the natural bond orbital (NBO) view, the valence bond perspective, the conceptual density functional theory, and relativity and chemical bonding.
A random sample of 120 students of 10th class was selected to explore students understanding regarding the concept chemical bonding. Seven instances or non-instances in total about this concept were developed to explore student's misconceptions.
of Timisoara, Romania) offers a unitary treatment of the main actual theories of matter: the Density Functional Theory for fermions, the Bose-Einstein Condensation for bosons, and the Chemical Bonding as a special realization of the first two in the so called mixed fermionic-bosonic states.
One of the most challenging parts of introductory high school or college biology courses is helping students understand basic chemical concepts, such as hydrogen bonds, polar and hydrophobic molecules, and chemical bonding. Most secondary school biology courses are taken prior to chemistry courses; at the college level, introductory chemistry is generally either a corequisite or is not required at all for introductory biology.

A final chapter explains how the bond valence model relates to and represents a simplification of other models of inorganic chemical bonding. Brown is professor emeritus at the Department of Physics and Astronomy, McMaster University, Canada.
In this way, the laser light pulse can be used to control the motion of electrons involved in chemical bonding and to change the outcome of a simple chemical reaction.
Cilbond chemical bonding systems, under constant development in both solvent- and water-based technologies, are available for the ultimate bonding of rubbers, plastics, metals, fabrics, glass, ceramics, composites and hybrid materials.
