  • metallic bonding
    • this is a regular lattice structure o= positive ions and - = sea of delocalised electrons.
    • Metallic Bond: The attraction of positive ions to delocalised electrons.
    • Properties
      • strong and dense
      • Conducts electricity and heat
      • malleable
      • Shiny when cut
      • Can be drawn out into wires
      • High melting and boiling point
    • METALS conduct electrcity because they can carry the charge as the delocalised electrons are free to move.
    • Metals have very high melting and boiling point so large amounts of energy are needed  to break down the  strong attraction between positive ions and the delocalised electrons.
    • WHEN ANSWERING QUESTIONS LOOK AT THE DELOCALISED ELECTRONS AND THE MORE DELOCALISED ELECTRONS THE STRONGER IT IS FOR THE  BOND TO BREAK
