    Electronegativity and Ionic Bonding
    ------------------------------------------
    An Ionic bond is the bond formed by the complete transfer of valence electron to attain stability.
    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 a strong attractive force between them. This force is an ionic or electrovalent bond.
    Ionic bonds form between atoms with large differences in electronegativity, whereas covalent bonds formed between atoms with smaller differences in electronegativity.
    The compound formed by the electrostatic attraction of positive and negative ions is called an ionic compound.
    Ionic Compound Properties
    ----------------------------------------
    Ionic compounds form when atoms connect to one another by ionic bonds.
    An ionic bond is the strongest type of chemical bond, which leads to characteristic properties.
    One atom in the bond has a partial positive charge, while the other atom has a partial negative charge. This electronegativity difference makes the bond polar, so some compounds are polar.
    But, polar compounds often dissolve in water. This makes ionic compounds good electrolytes.
    Due to the strength of the ionic bond, ionic compounds have high melting and boiling points and high enthalpies of fusion and vaporization.
