Metallic bond is a bond which is present between metals. Metallic bond is formed due to the interaction of delocalized electrons of metals. Same atoms are combined to form a metallic bond. These atoms lose electrons from their outer most shell. The free electrons in the metallic bond bound the positive charge or metallic nuclei. No electron is present in outer most orbit of an atom, so electrons are called delocalized electrons.
Covalent bond is formed by sharing electron pairs. Two atoms share electrons to complete their valence shell or to become stable. When two atoms share one electron pair, bond is called single covalent bond. If two electron pairs are shared, then bond is called double covalent bond. Triple covalent bond is formed when three electron pairs are shared by two atoms.
