- Connect structure to properties

## When to use me

- When learning inorganic chemistry basics
- When explaining element properties
- When studying periodic trends
- When understanding coordination compounds
- When preparing educational content

## Key Concepts

### Periodic Table Structure

- Groups (1-18): Similar valence electron configuration
- Periods (1-7): Same shell number
- Blocks: s, p, d, f based on orbital filling

### Chemical Periodicity

```python
# Example: Periodic trend calculations
periodic_trends = {
    'atomic_radius': {
        'across_period': 'decreases',
        'down_group': 'increases'
    },
    'ionization_energy': {
        'across_period': 'increases',
        'down_group': 'decreases'
    },
    'electronegativity': {
        'across_period': 'increases',
        'down_group': 'decreases'
    },
    'electron_affinity': {
        'across_period': 'generally increases',
        'down_group': 'generally decreases'
    }
}
```

### Acid-Base Concepts

**Arrhenius**
- Acid: H⁺ donor
- Base: OH⁻ donor

**Bronsted-Lowry**
- Acid: Proton donor
- Base: Proton acceptor

**Lewis**
- Acid: Electron pair acceptor
- Base: Electron pair donor

### Common Inorganic Compounds

- Acids: HCl, H₂SO₄, HNO₃, H₃PO₄
- Bases: NaOH, KOH, Ca(OH)₂
- Salts: NaCl, CaCO₃, NH₄NO₃
- Oxides: CO₂, SiO₂, Al₂O₃
