As a subject matter expert in the field of chemistry, I can provide you with a comprehensive explanation regarding the electrical conductivity of sodium. Sodium, with the chemical symbol Na, is an alkali metal and is found in Group 1 of the periodic table. It is a soft, silvery-white, highly reactive metal that is less dense than water. Understanding the electrical conductivity of sodium requires delving into the nature of its chemical bonds and the behavior of its ions.
Firstly, it is important to note that in its solid state, sodium is not a good conductor of electricity. This is due to the fact that in the solid crystalline structure of sodium, the atoms are held together by metallic bonds. These metallic bonds result from the delocalization of valence electrons across the lattice of metal cations. While this delocalization allows for the movement of electrons, in the solid state, the mobility of these electrons is restricted, which limits the metal's ability to conduct electricity.
However, when sodium is in a molten state or when it is dissolved in water, it becomes an excellent conductor of electricity. The reason for this change in behavior is the disruption of the metallic bonds. In the molten state, the sodium atoms gain enough kinetic energy to overcome the attractive forces of the metallic bonds, allowing the valence electrons to be free to move more independently. These free electrons can then carry an electric current, making molten sodium highly conductive.
When sodium is dissolved in water, it reacts vigorously to form sodium hydroxide (NaOH) and hydrogen gas (H2). This reaction is facilitated by the polar nature of water molecules, which can strip the valence electron from sodium, forming Na+ ions. These sodium ions are free to move in the solution and carry an electric current, thus making the solution conductive.
The reference to sodium's melting point is also pertinent. Sodium has a relatively high melting point of approximately 2,800°C. This high melting point is not directly related to its electrical conductivity but is a result of the strength of the metallic bonds in the solid state. The strength of these bonds is influenced by the size and charge of the ions involved. In the case of sodium, the Na+ ions have a single positive charge, which, while significant, forms weaker bonds compared to ions with higher charges, such as Mg2+ and O2- in magnesium oxide.
It is also worth mentioning that the electrical conductivity of sodium in a solution of sodium chloride (NaCl) is a result of the dissociation of NaCl into its constituent ions, Na+ and Cl-. In an aqueous solution, these ions are free to move and carry an electric current, which is why a solution of sodium chloride is conductive.
In summary, sodium's ability to conduct electricity is dependent on its state and the presence of a medium that allows for the movement of its ions. In the solid state, it is not conductive due to the restriction of electron movement by metallic bonds. However, in the molten state or when dissolved in water, sodium becomes highly conductive due to the mobility of its ions.

Non-conductive in its solid state, but when dissolved in water or molten NaCl will conduct electricity. Higher melting point than sodium chloride: around 2,800oC. This is because its Mg2+ and O2- ions have a greater number of charges, so they form stronger ionic bonds than the Na+ and Cl- ions in sodium chloride.
