  • Bonding
    • cannot exist alone but combine with other atoms
      • want to  make their outer shell complete ( Stable Octet)
    • Ionic Bonding
      • Occurs between Metal and  a non-metal
      • Made of Ions NegativeOr Positve
      • Transfer of electrons
        • Metals lose electrons while non metals gain
    • Covalent Bonding
      • Formed between two non metals
      • Diotomic elements are  Covalently bonded
      • only draw outer shell of elctrons
      • forces of attraction called van der Waals" forces
    • Metallic Bond
      • Attraction between  delocalised electrons and the positive ions
      • Definition
        • A layered structure of positive ions in a sea of delocalised electrons
  • forces of attraction called van der Waals" forces
  • Definition
    • A layered structure of positive ions in a sea of delocalised electrons
