Why doesn't N3- have a dipole moment arrow from the central atom?

Click For Summary
SUMMARY

The discussion centers on the Lewis structure of the azide ion (N3-), specifically addressing the absence of a dipole moment arrow from the central nitrogen atom to the other nitrogen atoms. Participants clarify that dipole moment arrows indicate the direction of electron density, typically pointing from a neutral atom to a negatively charged atom. The necessity of marking dipoles in Lewis structures is questioned, with one participant indicating that their instructor requires it to be done.

PREREQUISITES
  • Understanding of Lewis structures
  • Knowledge of molecular polarity
  • Familiarity with dipole moment concepts
  • Basic chemistry principles regarding ion charge
NEXT STEPS
  • Research the rules for drawing Lewis structures
  • Learn about molecular polarity and dipole moments
  • Study the properties of the azide ion (N3-)
  • Explore the significance of dipole moment arrows in chemical structures
USEFUL FOR

Chemistry students, educators, and anyone studying molecular structures and polarity in chemical compounds.

My teacher posted on his website, Lewis structures of different compounds. One of them were N3-

Why isn't there a dipole moment arrow pointing from the central atom to the other Nitrogen? Does the arrow only point from neutral atom to negatively charged atom?

I am not sure I understand your question.

First of all - is it obligatory to mark a dipole in the Lewis structure?

Don't know but He wants it done
