| Complex ions are ions that have a molecular structure consisting of a central atom bonded to other atoms by coordinate covalent bonds. |
|
| High temperatures are required, however, because the metal atoms grip the hydrogen with strong covalent bonds. |
|
| The tosylactivated beads form covalent bonds with any available primary amino or sulfhydryl groups. |
|
| The atoms in a polyatomic ion are held together by types of chemical bonds known as covalent bonds. |
|
| Each hydrogen bond between molecules is much weaker than the covalent bonds holding the atoms together within the molecule. |
|
| Dr. Leibler said conventional rubber consists of huge molecules with strong covalent bonds holding them together. |
|
| The two extremes of molecular bonding are ionic bonds and covalent bonds. |
|
| Pairs of electrons that are not shared in covalent bonds are lone pairs. |
|
| Block copolymers are polymers composed of two or more distinct chains, attached by covalent bonds. |
|
| When nonmetal atoms with differing electronegativities react, they form molecules with polar covalent bonds. |
|
| One could constantly pretend That chemistry's covalent bonds Were really lessons all about The power of emotional connection. |
|
| Others are multicentre covalent bonds, in which the bonding involves more than two atoms. |
|
| Molecular chemistry is the art of combining atoms by covalent bonds to build molecules. |
|
| Polysulfide, any member of a class of chemical compounds containing one or more groups of atoms of the element sulfur linked together by covalent bonds. |
|
| The molecules of these products consist of long chains in which polysulfide groups alternate with small organic groups capable of forming two covalent bonds. |
|
| Because the four subunits are so closely linked, the hemoglobin tetramer is called a molecule, even though no covalent bonds occur between the peptide chains of the four subunits. |
|
| The covalent bonds that attach reactive dye to natural fibers make them among the most permanent of dyes. |
|
| The highly directional nature of 5f orbitals is responsible for directional covalent bonds in molecules and complexes of plutonium. |
|
| Of the two, technetium more closely resembles rhenium, particularly in its chemical inertness and tendency to form covalent bonds. |
|
| Another similarity among the nitrogen elements is the existence of an unshared, or lone, pair of electrons, which remains after the three covalent bonds, or their equivalent, have been formed. |
|
|
|
| At the onset of lithiation, an isolated Li interstitial is found to form polar covalent bonds with four nearest host atoms, while the degree of covalency is noticeably greater for Li Si than Li Ge bonds. |
|
| Attempts have been made to describe the partial ionic character of covalent bonds on the basis of relative electronegativity of atoms. |
|
| Phosphine, PR3, is a three-coordinated organophosphorus compound comprising three covalent bonds and an unshared electron pair. |
|
| The d-orbitals from neighbouring ions overlap weakly into covalent bonds. |
|
| A comparison of boiling points for compounds formed by ionic and covalent bonds leads us to this conclusion. |
|
| The working principle consisted basically in obtaining chemical covalent bonds between the wood and the glue, that could guarantee the glueing process in any circumstance. |
|
| Termination: chain termination reactions occur when there is no reactive function available or not accessible, leading to a highly cross-linked solid coating in which all components are connected through covalent bonds. |
|
| Its chemical formula is H2O, meaning that its molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. |
|
| It was clear in theory that covalent bonds in biological molecules could provide the structural stability needed to hold genetic information in cells. |
|
| This is less applicable to compounds in which lead forms covalent bonds with elements of similar electronegativity such as carbon in organolead compounds. |
|
| After addition of NaIO 4 the catechol groups strongly interact with the thiol groups to form covalent bonds leading to a covalent network between alginate and pluronics. |
|
| Van der Waals forces are rather weak compared to covalent bonds. |
|
| Covalent bonds between the anomeric hydroxyl of a cyclic sugar and the hydroxyl of a second sugar are termed glycosidic bonds, and the resultant molecules are glycosides. |
