 Sorry to disagree (again) with you but I dont think that is a correct answer.
 Bonding
 changes the charge
 distribution not hybridization. Besides what do you mean by changing the charge
 distribution ?
 Comparing it with to the free atoms ? Orbital are models, and within these
 models we
 can describe
 chemical bonding with various approaches (MO or VB). Hybridization is only used
 in VB
 theory, because
 in MO the symmetry of the molecule plays an important role in determining the
 coefficients of the orbitals.
 Remember that to use hybrid-orbitals you must a priori know the geometry of the
 molecule.
