This is an interesting example of how students can evaluate resonance structures. The "chain" form of NO2F possesses no formal charges, but the "central N" structure should have resonance stabilization. Perhaps that principle is worth reinforcing with students: structures having multiple (resonable) resonance forms may be more stable. Figure 2.

R = H, alkyl, aryl. eg: Acylium ions are resonance stabilized.Mar 12, 2014 · You can draw multiple resonance structures, but keep in mind that there really aren't single bonds and a double bond in PO4^2-. All the bonds are identical due to delocalized pi-bonding. There are four resonance structures which use only single and double bonds. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Solid state 1H, 31P and 27Al Magic Angle Spinning (MAS) Nuclear Magnetic Resonance (NMR) was used in studies of surface species formed on synthetic fluorapatite in aqueous suspensions at different pH with or without ions or ion complexes of iron or aluminum in the suspension.
