Tell me about the atomic charges, dipole moment,
bond lengths,
angles,
bond orders,
molecular orbital energies,
or total energy.
Tell me about the best Lewis structure.
The Lewis structure is built for the up and down electrons,
separately. Note that the up and down structures can be very
different.
