Metallic Bond

                                 The reaction between molecules within metals are called alkali reactive force. It involve the sharing of free electrons among a lattice of metal atom.


  • Metals are strength, malleability, ductility, luster ( shiny appearance ) conduction of heat and electricity.
  • An alloy is a solution of metal , often used to make a metal rope, metal plates etc.
  • The electrons and the positive ions in the metal have a strong attractive force between them. So the metals have the high melting point Or boiling point.The principle is similar to that of ionic bonds.  
           The strength of metallic bond depends on three things.
  1. The number of electrons that becomes delocalized from the metal.
  2. The charge of the cation.
  3. The size of the cation.
  • Metals that are malleable can be beaten into thin sheets. For example aluminium foil.
  • Metals that are ductile can be drawn into wires. For example copper wire.
