I believe the correct answer from the choices listed above is option C. The type of substances that has <span>chemical bonds that are not directional and valence electrons that move freely between the atoms are metals. Hope this answers the question. Have a nice day.</span>
In metallic bonding there are delocalized electrons that are shared by a number of metal cations. The electrons are free to move and are not confined to a single metal cation. These free flowing electrons give metals its specific properties such as ductility, malleability, electrical conductivity and more.
