Is the idea here for you to know the Lewis electron dot structure?
Draw the Lewis structure, then determine the shape of the molecule.
In order for a molecule to be polar the following two criteria must be satisfied.

  1. There must be a difference in electronegativity between the central atom and one of the other atoms, AND
  2. The molecule must not be symmetrical in three dimensions. 0 0

    Those look ok to me. N2O is linear but polar. 0 0

so
N20 is polar
SO2 is polar
and N3- is ionic
?

I should have read the instructions as bob Pursley did.
