Molecular orbitals extending over more than two atoms provide an explanation for ionic bonding paramagnetism coordinate covalent bonding. resonance. Which of the following is not a valence bond concept? Atomic orbitals on two atoms may overlap to form antibonding orbitals. A pair of electrons in a bond is shared by both atoms. Lone pair electrons are in atomic orbitals or in hybrid atomic orbitals The greater the overlap between the orbitals on two atoms, the stronger the bond.
