Question

How does Sodium conduct thermal energy?

Answer 1

In a molten state the bonds become much weaker due to the increasedkinetic energy of the atoms, the electrons can move more freely, and the compound can conduct electricity.

Answer 2

-sodium metal demonstrates metallic bonding when it is in solid state. This means there is a 'sea of de localized electrons' that hold many positive ions in a lattice together. This sea of electrons are free to move around. When a potential difference is applied to the ends of the metal , the negative electrons are repelled away from the negative terminal and attracted to the positive terminal - thus allowing a current to flow.
