Back to basic. Covalent bond consist of single bonds, double bonds or triple bonds. Covalent bond are formed when non-metal atoms share electrons to achieve stable electron arrangements. Ionic bonds are formed through the transfer of electrons between atoms of metal and non-metal. Metal atoms donate electrons whereas non-metal atoms accept electrons to achieve the stable electron arrangement. Ionic compound can conduct electricity because electron are free to move but covalent compound cannot conduct electricity because the electron are not free to move. Besides, ionic compound have high melting and boiling points but covalent compound have low melting and boiling points. All the basic information i have stated obviously shows the different between those compound.
