Metallic bonds are able to conduct electricity only when they are dissolved in a liquid substance or when in molten, this is because these conditions cause the metallic bond to break down and allow the electrons used in the bond to be delocalised and disposited around the molten or liquid. This sea of free electrons is then able to pass through a current and conduct electricity.

RossMetals are very willing to exchange electrons. This electron exchange is electricity, and it leads to corrosion if two dissimilar metals are connected.
Metals are loosely bonded so they pass electricity at very low work done say electron volt (ev). Metals e.g. copper offer low opposition/resistance to the electricity due to more availaible free valance electrons in their outer most orbits as compared to other elements.
Because all the metallic atoms that share in a metallic bond have a weak grip on the valence electrons that they share in the form of an electron cloud (due to the low electronegativity of metals), the electrons are not very much attracted to any specific atom or location within the metal, and they therefore move easily. Since electricity is composed of moving electrons, electrical conductivity depends upon the ability of electrons to move easily.

Why metal is a conductor?
The metallic bonds which form the molecular structure of the metal solid are characterized by a virtually free flow of electrons between individual atoms, whereas non-metallic molecular bonds tend to keep the same electrons around each atom unless they are actively reacting. Consequently, when a source of electricity is applied to a metal, the free flow of electrons makes the conduction of charge, and in turn, electricity, much easier than it would be in a nonmetallic compound.
Does graphite conduct electricity?
It in-fact does conduct electricity, molten graphite is a key element in which terrorists use for I.E.D'S it causes a large heat blast when heated with electricity and mixed with different compounds.

What kind of bonds hold the chain of building blocks together?
The atomic covalent bonds that keep the building blocks joined together are of the same type as those that keep the chain-links linked.
