Which effect occurs when increasing the overlap integral between electronic wave functions of two atoms?

💡 Explanation

When overlap increases, greater electron density is shared between atoms because constructive interference enhances the probability of finding electrons in the bonding region, strengthening the covalent bond. Therefore, covalent bond strengthens, rather than increased ionization energy, weakened dispersion, or band gap widening which depend on separate physical parameters.
