Formula and methodology
Formula: Bond order = (bonding electrons - antibonding electrons) / 2.
The molecular-orbital bond-order expression compares electrons that stabilize a bond with electrons that oppose bonding. It is a simplified counting tool and does not by itself determine geometry, bond length, magnetic behavior, or spectroscopic properties.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Bonding electrons — minimum 0; maximum 1000000
- Antibonding electrons — minimum 0; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Bonding electrons | 8 |
| Antibonding electrons | 2 |
Bond order is 3.
Assumptions and limits
- The electron counts belong to one consistent molecular-orbital diagram.
- Bonding electrons are at least as numerous as antibonding electrons for this nonnegative bond-order contract.
- Nonbonding electrons and orbital degeneracy are not separately modeled.
