The bond present between metals is known as metallic bond. In metallic bond, all the atoms lose their valence electrons. These free electrons are known as delocalized electrons. No electron is present in valence shells of atoms which are involved in metallic bond. Delocalized electrons bound the positive charges or nuclei of atoms. Metallic compounds are good conductor of heat and electricity. They can conduct electricity due to the presence of free or delocalized electrons.
