Elements that are metallic lattice
WebMar 21, 2008 · A metallic lattice consists of positive ions in a 'sea' of outershell negative electrons which are delocalised and mobile through the metal structure. The lattice is held together by strong forces ... WebA metallic bond is a type of chemical bond in which a ‘cloud’ of free moving valence electrons is bonded to the positively charged ions in a metal. It can be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is entirely different from that of ionic and covalent bonds.
