Chapter Overview & Mind Map
This chapter explores the fundamental principles of atomic structure, bonding types, and molecular geometry. Master these concepts to understand how atoms connect and why molecules behave the way they do.
🗺️ Comprehensive Mind Map
🔬 Atomic Structure
- • Electrons in shells (1st: 2, 2nd: 8)
- • Valence electrons (bonding electrons)
- • Orbitals: s, p, d, f shapes
- • Energy levels determine reactivity
⚛️ Bonding Types
- • Ionic: electron transfer
- • Covalent: electron sharing
- • Metallic: delocalized electrons
- • Hydrogen: weak intermolecular
🔷 Molecular Geometry
- • VSEPR theory (electron repulsion)
- • Hybridization: sp, sp², sp³
- • Molecular shapes & bond angles
- • Polarity & molecular properties
