Formula and methodology
Formula: % ionic character = 100(1 − exp(−0.25(χA−χB)²)).
The Pauling estimate maps electronegativity difference to a percentage-like bond-character measure; it is not a direct charge measurement.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Electronegativity of atom A — minimum 0; maximum 10
- Electronegativity of atom B — minimum 0; maximum 10
Worked example
| Input | Value |
|---|---|
| Electronegativity of atom A | 2.2 |
| Electronegativity of atom B | 3.16 |
Estimated ionic character ≈ 20.7%.
Assumptions and limits
- Both electronegativities use the same Pauling scale.
- The result is an empirical estimate between zero and one hundred percent.
- Molecular geometry, bond environment, polarization, and partial-charge calculations are not represented.
