Key Topics to Revise
1
Introduction to Chemical Bonding
- Chemical bonds are forces that hold atoms together in compounds
- Two main types: ionic bonds (electron transfer) and covalent bonds (electron sharing)
- Outermost electrons (valence electrons) participate in bond formation
2
Kossel-Lewis Theory and Octet Rule
- Based on stability of noble gases with 8 valence electrons (octet)
- Atoms lose, gain, or share electrons to achieve noble gas configuration
- Hydrogen and lithium follow duplet rule (2 electrons like helium)
3
Ionic Bonding
- Formed between metals and non-metals with large electronegativity difference
- Complete electron transfer from metal to non-metal
- Electrostatic attraction between oppositely charged ions
4
Covalent Bonding and Lewis Structures
- Formed between non-metals by sharing electron pairs
- Each atom contributes one electron to shared pair
- Single, double, and triple bonds possible
