    I get why it forms Na+ but why doesn't it form a bond with the N- ?

    It does, but it will be primarily an ionic bond, not covalent

    Do you mean why isn't there a line between the N and the Na to show the bond?

    Well, a line represents a single covalent bond, which is not the type of bonding present in this case; it would be an ionic bond, shown by the N- and Na+ charges. (In ionic bonds, you don't draw a line).

    If the difference in electronegativity is high then it'll probably be ionic.
