How do you draw nitrogen in a newman projection? I have to draw a Newman projection for a molecule, sighting along the bond between a carbon and nitrogen. Given that the nitrogen is behind the carbon from this viewing angle, how would I depict the nitrogen? I know that I cannot draw it as a circle, as that represents carbon, so I am assuming that it is not possible to draw a Newman projection of this molecule from this particular angle. Is that a valid assumption?

And, if that is true, what would be considered an acceptable answer to that question? Should I just draw a standard 3D structure from the proposed viewing angle?
If it were up to me, I would:


Draw the nitrogen atom as if it were carbon but label it as "N".
Assuming normal valence  (e.g. an amine but not a nitro conpound), include the formally nonbonded electron pair as one of the substituents on nitrogen.
