Resource summary

C2 bonding
  1. Ionic bonding
    1. between metals and non metals
      1. Forms + and - ions
        1. Forms ionic compounds
          1. Giant ionic lattices
            1. Strong electrostatic forces of attraction
              1. High melting and boiling points
                1. Can dissolve in water
                  1. ions free to move conduct electricity
        2. Covalent bonding
          1. Between 2 non metals
            1. simple molecular substances
              1. weak inter molecular forces between molecules
                1. Very low melting/ boiling points to separates the molecules
                  1. don't conduct electricity no ions so no electrical charge
              2. Giant covalent structures
                1. Examples
                  1. Graphite
                    1. good conductor
                      1. 3 covalent bonds
                        1. each carbon atom 1 delocalised electron.
                          1. layers free to slide over each over. week intermolecular forces between layers
                        2. silicon dioxide
                          1. Diamond
                            1. each carbon 4 covalent bonds
                              1. very rigid and strong
                          2. Very high melting and boiling points
                        3. sharing electrons
                          1. Very strong bonds
                          2. Metalic structures
                            1. Alloys harder than pure metals
                              1. different elements have different sizes.
                                1. distort layers of metal atoms
                              2. giant structure
                                1. electrons delocalise
                                  1. allow the layers to slide over each over
                                    1. electrostatic attraction. positive metal ions + negative electrons
                                      1. conducts heat + electricity
                                  2. Isotopes
                                    1. Different atomic forms of the same element. Same number of PROTONS different number of neutrons
