Review of Short Phrases and Links

    This Review contains major "Chemical Bond"- related terms, short phrases and links grouped together in the form of Encyclopedia article.

Definitions

  1. A chemical bond is an attraction between atoms or molecules and allows the formation of chemical compounds, which contain two or more atoms.
  2. A chemical bond is an interaction which holds together atoms in molecules or crystals.
  3. A chemical bond is a concept for understanding how atoms stick together in molecules.
  4. A chemical bond is the multipole balance between the positive charges in the nuclei and the negative charges oscillating about them.
  5. A chemical bond is created between tooth and ceramic, restoring weakened teeth to their original strength.

Chemical Polarity

  1. Chemical polarity refers how polar a chemical bond is.

R--Ch

  1. Schiff base linkage: A chemical bond represented by R--CH.dbd.NH--R'.

Electron Deficient Chemical Bond

  1. A three-center two-electron bond is an electron deficient chemical bond where three atoms share two electrons.

Forms

  1. Thus, chemical bond ing between these elements takes many forms of electron-sharing that are more than simple electron transfers.

Sharing

  1. The exchange or sharing of the electrons between two or more atoms is the main cause of chemical bond ing.

Measure

  1. The bond dipole moment uses the idea of electric dipole moment to measure the polarity of a chemical bond within a molecule.

Form

  1. Gold and silver compounds are most commonly used for this purpose, because they form a chemical bond with the gallium at the surface of the wafer.

Breaking

  1. Chemical reactions usually involve the making or breaking of chemical bond s.

Break

  1. In biochemistry, a hydrolase is an enzyme that can break a chemical bond by hydrolysis.

Simple Sugars

  1. When two simple sugars are joined together by a chemical bond they are called disaccharides, the most common of which is sucrose or table sugar.

Carboxyl Groups

  1. The chemical bond formed between the carboxyl groups and amino groups of neighboring amino acids, constituting the primary linkage of all protein structures.

Electromagnetic Interactions

  1. The chemical bond between atoms occurs as a result of electromagnetic interactions, as described by the laws of quantum mechanics.

Proton

  1. Like ammonia, the amines are weak bases because the unshared electron pair of the nitrogen atom can form a coordinate bond with a proton (see chemical bond).
  2. The base takes a proton from the leaving group, forcing electrons to form a double chemical bond and break the bond to the leaving group.

Chemical Structure

  1. These two functional moieties are typically joined either directly to each via a chemical bond or through some chemical structure or spacer molecule.

Tooth

  1. The sealant is a hydrophilic resin acid-integrating network, which forms a chemical bond to the tooth and is placed in a wet environment.
  2. Primers allow the dentin's collagen fibers to be "sandwiched" into the resin, resulting in a superior physical and chemical bond of the filling to the tooth.

Bonding

  1. Bonding in dentistry technically means attaching a material substance to the tooth structure through a chemical bond.

Chemical Compounds

  1. In chemical compounds, the atomic nuclei of the component atoms remain distinct features of the molecule formed by the chemical bond or bonds.

Atom

  1. Dangling Bonds - A chemical bond associated with an atom on the surface layer of a crystal.

Formation

  1. The formation of water molecules, for instance, depends on the chemical bond between hydrogen and oxygen atoms.
  2. The formation of a chemical bond is only possible when more electrons occupy bonding orbitals than anti-bonding orbitals.

Chemistry

  1. In chemistry, regioselectivity is the preference of one direction of chemical bond making or breaking over all other possible directions.

Chemical

  1. A nucleophile participates in a chemical reaction by donating electrons to a species known as an electrophile in order to form a chemical bond.
  2. A chemical reaction or process which results in the formation of a chemical bond between a halogen atom and another atom.

Molecules

  1. Pantethine is actually two molecules of pantetheine joined by a disulfide bond (chemical bond between two molecules of sulfur).
  2. For example, crustal Earth rocks contain about 1--2 % water either as molecules trapped in the rock or as molecules in some kind of chemical bond.

Ethane

  1. The smallest alkane with such a chemical bond, ethane, exists as an infinite number of conformations with respect to rotation around the C-C bond.

Covalent Bond

  1. A chemical bond can be either a covalent bond, an ionic bond,a hydrogen bond or just because of Van der Waals force.

Carbon

  1. Carbon has the ability to form a chemical bond with a wide variety of chemical elements and other carbon atoms.
  2. In steam cracking, initiation usually involves breaking a chemical bond between two carbon atoms, rather than the bond between a carbon and a hydrogen atom.
  3. The Schmidt reaction is an organic reaction involving alkyl migration over the carbon to nitrogen chemical bond in an azide with expulsion of nitrogen [1].

Single Bonds

  1. Valspar patents coating composition by Coatings World any of a group of aliphatic hydrocarbons whose molecules contain only single bonds (see chemical bond).

Molecule

  1. In a bimolecular substitution, a nucleophile, which is a reagent that forms a chemical bond, replaces another atom attached to a molecule.
  2. In chemistry, valence bond theory explains the nature of a chemical bond in a molecule in terms of atomic valencies.
  3. The carbon of the carbonyl has a lone electron available, with which it forms a chemical bond to the remainder R of the molecule.

Atoms

  1. Atomic radii may be derived from the distances between two nuclei when the two atoms are joined in a chemical bond.
  2. The bonding holding the ligands to the central atom or ion is similar to covalent bonding between atoms but is more complex (see chemical bond).
  3. To the south of the carbon atom (C) is a hydrogen atom (H), which, like all the other atoms or groups, is joined to the carbon center by a chemical bond.

Electrons

  1. Covalent Bond - A chemical bond formed by the sharing of electrons between atoms.
  2. Electrons in bonding orbitals result in the formation of a chemical bond, while those in anti-bonding orbitals prevent bonding.
  3. Electron pair Two electrons within one orbital with opposite spins responsible for a chemical bond.

Chemical Bond

  1. Each molecule of water, for example, consists of a single atom of oxygen and two atoms of hydrogen joined by an electrical force called a chemical bond.
  2. Electronegativity is a measure of the ability of an atom or molecule to attract electrons in the context of a chemical bond.
  3. In Valence Bond Theory, a chemical bond between two atoms is the result of direct overlap of two atomic orbitals (one on each atom).
