Key Questions

  • Answer:

    The complete transfer of electrons(valence) is called as ionic bond.
    Here is the brief description:-


    When opposite charged ions interact with each other they transfer their own valence electron completely to the opposite charged particle thus developing a electrostatic attraction between the two ions.This type of chemical bonding is called as Ionic Bonds.

    This process makes one atom electropositive in nature( loss of electron called as CATION) and the other atom being electronegative in nature(gain of electron called as ANION).

    One example can be:-

    Na and F atom undergo ionic bonding where,
    Na donates its 1 valence electron to Fluorine thus becoming CATION whereas sue to the gain in the electron Fluorine becomes ANION.

    Some of the properties of the ionic bonds are:-
    =>They have a very high rate of boiling and melting point.
    =>They have a strong force of attraction between them.

  • Answer:

    Brief Answer ahead with points on the importance of ionic bonds:-


    The main significance of the ionic bonds are:-

    =>Most of the organic compounds are synthesized due to presence of ionic bonds. By this type of bonding it is now easier to know their interactions to produce specific compounds.

    =>This type of bonding tend to hold differently charged atoms (i.e. the metals and the non metals) which facilitates the many types of objects all around us. For example the salt u eat!!

    =>Ionic bonds are also responsible for the dissolving of the compounds in their respective polar solvents.

  • Answer:

    Ionic and covalent bonds differ in the degree of the sharing of the electron density between the atoms involved in the bond.


    Chemical bonds are formed by the sharing of electron densities between two atoms. The electron density of the atoms is held between the two atoms and attracted to the positive forces of both sets of protons in the two nuclei.

    In Ionic bonds there is a large difference in electronegativity between the two atoms ( greater than 1.7) The large difference in electronegativity results in most of electron density being located next to the atom with the greatest electronegativity, and very little electron density being next to the atom with the lower electronegativity. This makes it easy for the two atoms involved int the bond to separate leaving one atom with a positive charge and one atom with a negative charge.

    In covalent bonds there is no difference or a small differences in electronegativity. The electron density is more evenly shared between the two atoms. This creates a stronger bond between the two atoms that is more difficult to separate. Atoms involved in covalent bonding do not separate into ions.

    Ionic and covalent bonds differ in the degree of sharing of the electron densities between them. Covalent bonds share the electrons more equally and are stronger. Ionic bonds share the electrons very unequally and can be broken into ions.
