Molecular Orbital Diagram
Captions available
The idea
A molecular orbital diagram ranks a molecule's bonding and antibonding orbitals by energy and fills them using the same Aufbau, Pauli, and Hund rules.
In practice
Nitrogen's ten valence electrons fill the diagram's ranked orbitals lowest-energy first, completing the bonding and antibonding orbitals in energy order.
Where people slip
The same three filling rules from atomic configuration carry over unchanged; no new filling procedure applies.
