  • Bonding
    • Covalent Bond: shared pair of electrons
      • Dative covalent bond: shared pair of electrons in covalent bond come from one of the bonding atoms
        • Examples:
        • direction of arrow goes from atom providing the lone pair to atom that is deficient.
  • Metallic Bonding:  electrostatic force of attraction between the positive metal ions and delocalised electrons

      • Covalent Bond: shared pair of electrons
        • Dative covalent bond: shared pair of electrons in covalent bond come from one of the bonding atoms
          • Examples:
          • direction of arrow goes from atom providing the lone pair to atom that is deficient.
    • three main factors affecting the strength of bonding:
      • 1)number of protons/strength of nuclear attraction (more protons, stronger bond)
      • 2) number of delocalised electrons per atom (outer shell electrons are delocalised) (the more there are, stronger bond)
      • 3) size of the ion (stronger when ion smaller)
