metallic crystal The type of crystal formed by most metals, in which the outer electrons are shared by the crystal as a whole. Thus, the positively charged metal ions in the crystal lattice are surrounded by a "gas" of free electrons. These free electrons account for the fact that most metals are good conductors of heat and electricity.
