The valence-bond model cant adequately explain the fact that some molecules contains two equivalent bonds with a bond order between that of a single bond and a double bond. 2). Delocalized valence electrons produce metallic bonds (bonds between atoms of metals) which give metals unique properties such as conductivity and ductility (draw metal into wires). In general, without chemical bonds, life would be completely different. A valence electron can either absorb or release energy in the form of a photon. Placing an electron in this orbital therefore stabilizes the H2molecule.
