Explanation:
Highly directed bonds:
Metallic bonds are not highly directed bonds like covalent or ionic bonds. In metallic bonding, the valence electrons of metal atoms are delocalized and free to move throughout the structure. This results in a sea of mobile electrons that are not localized between specific atoms, as seen in covalent or ionic bonds.
Metallic bonds are characterized by a more non-directional nature, allowing for the mobility of electrons throughout the metallic lattice. This delocalized electron cloud gives metals their unique properties such as malleability, ductility, and electrical conductivity.
In contrast, highly directed bonds refer to bonds where electrons are localized between specific atoms and have specific directional arrangements. Metallic bonds do not exhibit this high level of directionality, hence the statement that "highly directed bonds" do not apply to metallic bonding.
Therefore, option 'D' - Highly directed bonds, does not apply to metallic bond.
