Why can Na conduct electricity more than Lithium

Question

I am a student in form two ,fifteen years old.I am a Kenyan 

Answer 1

Each atom of Na has 11 electrons.  Each atom of Li has 3 electrons.  They both form metallic bonds with other like atoms, and thus there are more "free", unassociated electrons in Na metal than in Li metal.  The more electrons, the better conductor.
