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
