    • BONDING
      • METALLIC
    • Positively and negatively charged ions bond together to cancel out charges.
  • COVALENT
    • INTERMOLECULAR
      • Shared pair  of electrons between two atoms
        • COVALENT
        • Bond is between two non metals such as H20
          • Sometimes dative covalent bonds form
            • Dative Covalent is where both electrons donated come from one atom such as NH4+
          • Electrostatic force of attraction between positive metal ions and delocalised electrons
            • The positive metal ions are attracted to the electrons to form a lattice and metallic bonding
              • Formed between metal and non metal ions.
                • IONIC
                  • Positively and negatively charged ions bond together to cancel out charges.
              • Strong electrostatic force between oppositely charged ions.
                • Three different types- Van Der Waals,Hydrogen and dipole-dipole.
                  • INTERMOLECULAR
                    • Dipole Forces are forces between the positive end of one polar molecule, and the negative end of another polar molecule.
                  • Van der Waals' forces are forces of attraction that exists between all atoms and molecules. It is the weakest of the forces.
                    • Three different types- Van Der Waals,Hydrogen and dipole-dipole.
                      • Dipole Forces are forces between the positive end of one polar molecule, and the negative end of another polar molecule.
                  • Sometimes covalent bonds are polar, and so the shared pair of electrons are not equally shared
                    • One atom will attract the pair of electrons more than the other, depending on its electronegativity
