Formula and methodology
Formula: Electron count = atomic number−ionic charge, filled in the aufbau orbital order.
The calculator returns a compact orbital-occupancy string and the electron count used to generate it.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Atomic number — minimum 1; maximum 118
- Ionic charge — minimum -10; maximum 10
Worked example
| Input | Value |
|---|---|
| Atomic number | 17 |
| Ionic charge | 0 |
Electron configuration = 1s² 2s² 2p⁶ 3s² 3p⁵.
Assumptions and limits
- Atomic number and charge are whole numbers and the resulting electron count is between 1 and 118.
- The displayed order is a simplified ground-state filling order and does not encode every known transition-metal exception.
- Excited states, relativistic effects, molecular orbitals, and spectroscopy are not modeled.
