  -Kossel and Lewis(1916) gave their Electronic theory of bonding to explain the formation of bonds between atom`s. -The atoms of some elements have incomplete last orbits and they tend to achieve the inert gas configuration(2,8,18,32,64). -Tendency of atoms to acquire inert gas electronic configuration will causes the atoms to unite too form the chemical bonds. -Inert gas configuration involves electronic grouping of two or eight electrons which can be achieved by the combining 2 or more atoms either by losing, gaining or sharing electrons among themselves.

  To attain thestable inert gas electronic configuration by atoms ,Three types of chemical bonds are formed. Types Of Chemical Bonds Ionic Bond Covalent Bond Coordinate Bond

  Ionic Bonding orlook linkage- This type of chemical bonding is formed when complete transference of one or more electrons from one atom to the other takes place so that both the atoms acquire inert gas electronic configuration. The atom that loses the electron/s becomes positively charged and the atom that gains the electrons becomes negatively charged. The charged Species (called ions) thus produced are held together by electrostatic force of attraction. 2,8,1 2,8,7 2,8 2,8,8

  Covalent Bonding orCovalent Linkage-This type of bonding is formed between atoms which have similar or identical electronegativities. Here the sharing of electrons takes place between the two or more atoms to attain the inert gas configuration. This type of bonding comes into existence by mutual sharing of electrons, it is called a Covalent bonding. A covalent bonding or bond is usually signified b y a horizontal line (—).

  Coordinate bond- Itis a special type of covalent bond in which both the shared electrons are contributed by one atom only. The atom that donates the electron pair donor atom) has a spare unshared pair of electrons in the outer orbit and the one that accepts (acceptor atom) is short by an electron pair. However, after the formation of the bond, the electron pair involved is held in common and counts towards both the atoms. A coordinate bond is represented by an arrow, pointing away from the donor atom and towards to acceptor atom.
