Metal keys
Metal bonds are in the chemical bond, mainly in the presence of metal, some of the cluster compounds also exist in the metal bond. By the combination of free electrons and electrostatic attraction between the metal ions arranged in a lattice form. Due to the free movement of electrons, the metal keys do not have a fixed direction and are therefore non-polar. Metal bonds determine many physical properties of the metal, such as strength, plasticity, ductility, conduction heat, conductivity and luster. For example, the melting point of the general metal, the boiling point with the strength of the metal bond increased. The smaller the ion radius, the stronger the metal bond. ...
