WebMar 26, 2014 · Metallic bonds involve all of the metal atoms in a piece of metal sharing all of their valence electrons with delocalized bonds. This is different from ionic bonding (where no electrons are shared at all) and covalent bonding (where the bonds exist only between two atoms). A metal that you can hammer into thin sheets is malleable.
