7th Ed. 2.7: Most important Lewis structure

[Julia Lindner 1I]

The question says to draw the "most important Lewis structure" for N5+, including all equivalent resonance structures. What does it mean by most important? Also, why is the most important structure the one with a -1 charge on the central atom instead of a 0 charge?

I think that this means the lewis structure with the correct bond angles and the correct number of bonds to lone pairs. Sometimes the central atom will have a formal charge that is non-zero in order to satisfy the other atoms that is bonded to.

The most important lewis structure would be the most stable, lowest energy lewis structure with the right bond angles.
