ionic bond: see chemical bond chemical bond, mechanism whereby atoms combine to form molecules . There is a chemical bond between two atoms or groups of atoms when the forces acting between them are strong enough to lead to the formation of an aggregate with sufficient stability to be regarded as ..... Click the link for more information. . ionic bondElectrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when one or more electrons are transferred from one neutral atom (typically a metal, which becomes a cation) to another (typically a nonmetallic element or group, which becomes an anion). The two types of ion are held together by electrostatic forces in a solid that does not comprise neutral molecules as such; rather, each ion has neighbours of the opposite charge in an ordered overall crystalline structure. When, for example, crystals of common salt (sodium chloride, NaCl) are dissolved in water, they dissociate (see dissociation) into two kinds of ions in equal numbers, sodium cations (Na+) and chloride anions (Cl−).

This was attributed to the very stable ionic interaction of ZDA with the carboxylate group of HXNBR, which together provided exceptional reinforcing properties. In addition to the absorption process, the negatively charged polymer is also capable of selective bonding with positively charged substances through ionic interaction. DMF is known as a polar solvent that disrupts ionic interactions (ref 11). |
