IONIC OR ELECTROVALENT BOND PDF DOWNLOAD!
Ionic or Electrovalent Bond. The bond formed by this kind of combination is an ionic bond or electrovalent bond. An Ionic bond is the bond formed by the complete transfer of valence electron so as to attain stability. This type of bonding leads to the formation of two oppositely charged ions. Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. Ionic Bond or Electrovalent Bond Two or more atoms unite together to form a molecule. Get introduced to ionic bonding, its definition, properties.

Atoms that are weakly electronegative such as alkali metals have relatively few valence electrons, which can easily be shared with atoms that are strongly electronegative.
As a result, weakly electronegative atoms tend to distort their electron cloud and form cations. Formation[ edit ] Ionic bonding can result from a redox reaction when atoms of an element usually metalwhose ionization energy is low, give some of their electrons to achieve a stable electron configuration.
In doing so, cations are formed. An atom of another element usually nonmetal with greater electron affinity accepts the electron s to attain a stable electron configuration, and after ionic or electrovalent bond electron s an atom becomes an anion.
Ionic bonding - Wikipedia
Typically, the stable electron configuration is one of the noble gases for elements in the s-block and ionic or electrovalent bond p-blockand particular stable electron configurations for d-block and f-block elements.
The electrostatic attraction between the anions and cations leads to the formation of a solid with a crystallographic lattice in which the ions are stacked in an alternating fashion.
In such a lattice, it is usually not possible to distinguish discrete molecular units, so that the compounds formed are not molecular in nature. However, the ions themselves can be complex and form molecular ions like the acetate anion or the ammonium cation.
For example, common table salt is sodium chloride. These ions are then attracted to each other in a 1: For compounds that are transitional to the alloys and possess mixed ionic and ionic or electrovalent bond bonding, this may not be the case anymore.
Ionic Bond Or Electrovalent Bond
Representation of ionic bonding ionic or electrovalent bond lithium and fluorine to form lithium fluoride. This type of bonding leads to the formation of two oppositely charged ions — positive ion known as cations and negative ions are known as anions.
The presence of two oppositely charged ions results in strong attractive force between them. This shows that its octet is complete. Cl-atom needs one electron to complete its octet. Electron ionic or electrovalent bond by Ionic or electrovalent bond atom picks up by Cl atom.
Electronic arrangement after acquiring an electron: In ionic crystalline solids of this kind, the electrostatic forces of attraction between opposite charges and repulsion between similar charges orient the ions in such a manner that every positive ion becomes surrounded by negative ions and vice versa.
In short, the ions are so arranged that the positive and negative charges alternate and balance one another, the overall charge of the entire substance being zero.
The magnitude of the electrostatic forces in ionic crystals is considerable.
