Concept
Formal charge is a theoretical charge assigned to atoms within a molecule, calculated by assuming equal sharing of bonding electrons. It is used to predict the most stable structure of a molecule by minimizing the Formal charges across the atoms.
Concept
Bond order is a measure of the stability and strength of a chemical bond, calculated as the difference between the number of bonding and antibonding electrons divided by two. A higher bond order indicates a stronger bond and typically correlates with shorter bond lengths and higher bond energies.
