to conduct electricity, you need to be able to have 1. movement and 2. charged particles

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

Ok, well sodium is a metal so it has a 'sea' of delocalised electrons which can move from one end of the metallic sructure to the other when a voltage is applied. Electrons are charged (negatively) so as they move they can carry a charge therefore sodium can conduct electricity.

Same way as any other metal.

Because it has a negative polarity i think?!
