inorganic

## What I do - Explain properties of elements and compounds - Describe periodic trends and reactivity - Discuss coordination chemistry basics - Analyze acid-base chemistry - Explain redox chemistry - 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
