As a materials science expert, I can explain why metals conduct electricity in their molten state. Metals are unique in their ability to conduct electricity due to their atomic structure. The key to understanding this phenomenon lies in the arrangement of atoms and the behavior of electrons within the metal.
Metals have a crystalline structure where atoms are arranged in a regular, repeating pattern. Each metal atom contributes one or more valence electrons to a "sea" of electrons that are free to move throughout the structure. These valence electrons are not tightly bound to any particular atom; instead, they are delocalized and can move freely across the entire material. This "sea" of delocalized electrons is what gives metals their characteristic ability to conduct electricity.
When metals are in a molten state, their atoms are still arranged in a crystalline pattern, albeit a disordered one. Despite the increased disorder and the fact that the atoms are more loosely packed, the valence electrons remain delocalized and can still move freely. This is because the forces that bind the electrons to the atoms are not strong enough to restrict their movement. The ionic bonds mentioned in the reference are not applicable here, as metals do not form ionic bonds in their conductive state. Instead, the metallic bonds, which are non-directional and allow for the free flow of electrons, are what facilitate conductivity.
The conductivity of metals in the molten state can also be influenced by factors such as temperature and impurities. As temperature increases, the movement of atoms and electrons becomes more vigorous, which can enhance the conductivity. However, if impurities are present, they can disrupt the flow of electrons and reduce conductivity.
It's important to note that not all metals have the same level of conductivity. Some metals, like copper and silver, are excellent conductors, while others, like stainless steel, are less so. The difference in conductivity among metals is due to the number of valence electrons available for conduction and the strength of the metallic bonds.
In summary, metals conduct electricity in their molten state because of the delocalized valence electrons that can move freely within the metallic bond structure. This ability is a fundamental property of metals and is what makes them indispensable in various applications, from electrical wiring to heat sinks.

One of the properties of metals is that they can conduct electricity in solid and molten state. Sodium's sea of delocalized electrons among the unipositive ions present in the structure is what gives it its conductivity. ... This is because ionic bonds are rigid and do not allow for free flow of electrons.
