Covalent bond— A chemical bond formed when two atoms share a pair of electrons with each other. Element— A pure substance that can not be changed chemically into a simpler substance. Ionic bond—The attractive forces between positive and negative ions that exist when electrons have been transferred from one atom to another.

Am. (ci) An ion is a charged atom or group of atoms an ionic bond is the attraction between ions. 

The word bonding applies to any situation in which two or more atoms are held together in such close proximity that they form a characteristic species which has distinct properties and which can be represented by a chemical formula. In compounds consisting of ions, bonding results from the attractions between the oppositely charged ions. In such compounds in the solid state, each ion is surrounded on all sides by ions of the opposite charge. (For example, see Fig. 5-1.) In a solid ionic compound, it is incorrect to speak of a bond between specific pairs of ions. 

Processes accompanied by a decrease in volume, such as C—C bond formation, in which the distance between two carbon atoms decreases from the van der Waals distance of ca 3.6 A to the bonding distance of ca 1.5 A, are accelerated by raising the pressure and equilibria are shifted toward the side of products (AV < 0, AV < 0). The reverse reaction, a homolytic bond cleavage, leads to an increase in volume (AV / > 0, AV > 0). Pressure induces a deceleration of such a process and a shift in equilibrium toward the side of reactants. However, in an ionization, such as an ionic dissociation, the attractive interaction between the ions generated and the solvent molecules leads to a contraction... 

Also attracting growing attention is the phase coexistence curve characteristic of ionic systems it plays a role in some ionic solution phenomena, although examples in aqueous solutions are not known at this time. Other new features are the intense concentration dependence - at low concentration - of certain of the Hamed coefficients that characterize mixed electrolyte solutions and the evidence for a solvent-separated state of the hydrophobic bond, the attractive force between hydrophobic ions, even those of zero charge, in water. 

The attraction between oppositely charged ions results in an ionic bond, such as the one that holds NaCl together. The oppositely charged ions Na+ and CP, attract each other in such an ordered manner that a crystal results (fig. 3). 

When two or more ions bond together chemically, it is called an ionic bond. In an ionic bond, the ions are attracted to one another because they have opposite charges. In general, ionic bonds form between a metal and a nonmetal. Since sodium is a metal and chlorine is a nonmetal, when they bond, an ionic bond is formed and sodium chloride is produced.
