## Key Concepts

### Periodic Trends

- Atomic radius: Decreases across period, increases down group
- Ionization energy: Increases across period
- Electronegativity: Increases across period
- Electron affinity: Varies across period
- Oxidation states: Variable for transition metals

### Coordination Chemistry

**Ligand Types**
- Monodentate: Single donor atom (NH₃, H₂O, Cl⁻)
- Bidentate: Two donor atoms (en, oxalate)
- Polydentate: Multiple donor atoms (EDTA)
- Ambidentate: Multiple binding modes (SCN⁻, NO₂⁻)

```python
# Example: Crystal field stabilization energy
def cfse(electron_config, geometry):
    """
    Calculate crystal field stabilization energy.
    electron_config: d-electron count
    geometry: 'octahedral' or 'tetrahedral'
    """
    if geometry == 'octahedral':
        # For 6-coordinate: t2g ↑↓↑↓↑↓ > eg ↑↑
        return {'d0': 0, 'd1': -4, 'd2': -8, 'd3': -12,
                'd4': -6, 'd5': 0, 'd6': -4, 'd7': -8,
                'd8': -12, 'd9': -6, 'd10': 0}
    elif geometry == 'tetrahedral':
        # For 4-coordinate: e ↑↓ > t2 ↑↑
        return {'d0': 0, 'd1': -6, 'd2': -12, 'd3': -8,
                'd4': -4, 'd5': 0, 'd6': -6, 'd7': -12,
                'd8': -8, 'd9': -4, 'd10': 0}
```
