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⁻)
