Metallic bond This is bonding of metal atoms where positive metal ions are in a three-dimensional arrangement and the valence electrons are able to move freely over the entire structure of the metal.

The force of attraction between a positively charged metal ion and the valence electrons it shares with other ions of the metal is called a(n) metallic bond.
