Draw the Lewis structures for the nitrate ion. (There are three resonance structures.) Using these Lewis structures describe the bonding in the nitrate ion.

What is the geometry about all of the atoms: what is the geometry about the central N atom? What is the electron domain geometry of the oxygen atoms?

What are the hybrid orbitals on the N and O atoms in the ion?b) How many sigma bonds are in this ion?

Which orbitals overlap to form these bonds?c) Describe the pi bonding in this ion. How many electrons are involved in the delocalized system? How can you tell from the resonance forms of the Lewis structure?
