Which of the following statements summarizing valence bond theory is correct? The geometry of the molecule is determined by the geometry of the orbitals used. The orbitals used in bond formation are atomic orbitals (s, p, d, and f). A chemical bond forms only when occupied orbitals are involved. A bond is formed by the overlap of two hybrid orbitals or two atomic orbitals.
