The Strongest chemical bond is the ionic bond ,
Because ionic bond is bound by strong electrostatic interactions ,
The ionic bond forms crystal lattice structure which are bounded by electrostatic interactions but the covalent bond is formed by the van der waal forces .
Hence , ionic bond is stronger than covalent bond .
