(a) Interpretation: Two non-metals that can form more than four bonds should be located on the periodic table. Concept introduction: In order to form more than four bonds, an element should be able to expand its valence shell to occupy more than eight electrons. In some third row elements tend to form more than four bonds because of the existence of d sublevels. These d orbitals can accommodate more electrons.
