Key Topics to Revise

1

Kossel-Lewis Approach and Octet Rule

  • Noble gases are chemically inert due to their stable electronic configuration (ns²np⁶)
  • Atoms achieve stability by gaining, losing, or sharing electrons to attain noble gas configuration
  • Lewis symbols represent valence electrons as dots around the atomic symbol
2

Ionic (Electrovalent) Bonding

  • Forms between metal and non-metal atoms
  • Complete transfer of electrons from metal to non-metal
  • Metal becomes cation (+ve), non-metal becomes anion (-ve)
3

Covalent Bonding and Bond Parameters

  • Forms by sharing of electron pairs between atoms
  • Can be single, double, or triple bonds
  • Polar covalent bonds form between atoms of different electronegativity
4

VSEPR Theory

  • Molecular geometry depends on electron pair repulsions around central atom
  • Electron pairs arrange themselves to minimize repulsion
  • Repulsion order: lp-lp > lp-bp > bp-bp
