Versuch eines Lehrbuchs der Stöchiometrie - Heinrich Buff 1829 Die Struktur wissenschaftlicher Revolutionen - 2009 Webmetallic bondA chemical bond in which mobile electrons are shared over many nuclei; this leads to electrical conduction. Metallic Bonding Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds.
