The basis of the VSEPR model of molecular bonding is . Question 1 options: atomic orbitals of the bonding atoms must overlap for a bond to form regions of electron density in the valence shell of an atom will arrange themselves so as to maximize overlap electron domains in the valence shell of an atom will arrange themselves so as to minimize repulsions hybrid orbitals will form as necessary to, as closely as possible, achieve spherical symmetry regions of electron density on an atom will organize themselves so as to maximize s-character
