... METALIC BONDING Metallic bonding occurs between atoms with low electronegativity (.i.e. 1, 2 or 3 valence electrons); therefore there are many vacancies in valence shell. The crystal lattice of metals consists of ions NOT atoms. When electron clouds overlap, electrons can move into electron cloud of adjoining atoms. The outer electrons (-) from the original metal atoms are free to move around between the ... The attractions between the solvent molecules and the ions aren't big enough to overcome the attractions holding the crystal together. Ionic compounds do not conduct electricity, beca...
