Using the figure above, determine which of the following statements are true.

Select ALL that apply.

A

The formal charge of the nitrogen atom is +1 and its oxidation state is +3.

B

It would be expected that the molecule has two different N-O bond lengths, a longer bond due to the N-O and a shorter one due to the N=O.

C

The electron pair and the molecular geometry about the nitrogen atom are both trigonal planar.

D

The O-N-O bond angle would be expected to be approximately 120${ }^{ \circ }$.
