Web5 sep. 2024 · Answer: The covalent bond is stronger than the ionic bond. The covalent bond is formed by sharing of electrons. There is an atomic orbital overlapping occurring in two bond-forming atoms and a sigma bond is formed. The bond length is small, hence the influence of attractive force is greater and atoms get closer.
