ionic bond, also called electrovalent bond, kind of linkage created from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond develops when the valence (outermost) electrons of one atom space transferred permanently to an additional atom. The atom the loses the electrons becomes a positively fee ion (cation), while the one the gains them i do not care a negatively fee ion (anion). A short treatment that ionic binding follows. For full treatment, see chemistry bonding: The formation of ionic bonds.
Ionic bonding results in compounds known as ionic, or electrovalent, compounds, i m sorry are finest exemplified by the compound formed between nonmetals and the alkali and alkaline-earth metals. In ionic crystalline solids of this kind, the electrostatic pressures of attraction in between opposite charges and repulsion between comparable charges orient the ion in together a manner the every confident ion becomes surrounded by an unfavorable ions and also vice versa. In short, the ions room so arranged the the optimistic and an adverse charges alternative and balance one another, the all at once charge the the entire substance being zero. The size of the electrostatic pressures in ionic crystals is considerable. Accordingly, these substances have tendency to it is in hard and also nonvolatile.
Sodium chloride exhibits ionic bonding. The salt atom has a solitary electron in that outermost shell, when chlorine needs...
An ionic shortcut is in reality the extreme case of a polar covalent bond, the latter resulting from unequal sharing of electrons quite than finish electron transfer. Ionic bonds typically form when the distinction in the electronegativities of the 2 atoms is great, when covalent bonds form when the electronegativities are similar. Compare covalent bond.
