Such bonds, which result from the transfer of electrons, are not formed between particular ions but exist between an ion and all of the oppositely charged ions in its immediate vicinity. Very few materials have bonds that at truly ionic; most ionic bonds are, at least, partially covalent. The fraction of ionic character of a bond, f, can be estimated from the electronegativities (X) of the two atoms according to the formula: Related category    • PHYSICAL CHEMISTRY Also on this site: Encyclopedia of Alternative Energy & Sustainable Living Encyclopedia of History Transport Concepts & Designs (partner site) BACK TO TOP
