Bond Order Calculator
e⁻
Number of electrons in bonding molecular orbitals
e⁻
Number of electrons in antibonding molecular orbitals
Bond Order: 1.0
The molecule has a single bond between the atoms.
This bond is stable.
Common Molecular Bond Orders
| Molecule | Bonding Electrons | Antibonding Electrons | Bond Order |
|---|---|---|---|
| H₂ | 2 | 0 | 1 |
| He₂ | 2 | 2 | 0 |
| O₂ | 10 | 6 | 2 |
| N₂ | 10 | 4 | 3 |
| F₂ | 10 | 8 | 1 |
How It Works
+
Bond order is a measurement of the number of electrons involved in bonds between two atoms.
The formula for calculating bond order is:
Bond Order = (Number of bonding electrons – Number of antibonding electrons) / 2
Where:
- Bonding electrons are electrons in molecular orbitals that stabilize the molecule
- Antibonding electrons are electrons in molecular orbitals that destabilize the molecule
Interpretation of bond order values:
- Bond Order = 0: No bond forms (molecule is unstable)
- Bond Order = 1: Single bond
- Bond Order = 2: Double bond
- Bond Order = 3: Triple bond
- Bond Order > 0: Higher values indicate stronger, shorter bonds
