electronsof oneatomare transferred permanently to another atom. The atom that loses theelectronsbecomes a positively chargedion(cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows. For full treatment,seechemical bonding: The for...
Alkaline-earth metal - Ionic Character, Bonding, Reactivity: The chemistry of the alkaline-earth metals, like that of the alkali metals, is for the most part reasonably interpreted in terms of an ionic model for the compounds formed. This model is less s

At pH 2.5, the relatively high viscosity of uncross-linked HA solutions has been attributed to stiffness of individual chains due to a critical balance between attractive (H-bonding) and repulsive (anionic) forces and later to interchain association as evidenced by a minimum in its self-...

Finally, using density functional theory, we could confirm the stability of the ordering observed by AFM and gain additional insight into the nature of the bonding and how charge in the Stern layer changes with solution composition. Results The gibbsite particles were deposited from a water-ethanol...
Due to the many possible combinations (>×106) of cations and anions, questions are raised regarding how to identify the optimum ion pairing for a specific application. However, thanks to the intensive free-to-access database, ILThermo, generated and updated by the National Institute of ...
While electrostatic interactions act over long distances, the shorter-range nature of polar hydrogen-bonding forces, combined with steric packing and hydration, provide additional methods for controlling self-assembly. The effects we have presented here raise obvious follow-on questions about the effects...
