AQA GCSE Chemistry 2
  1. Structure and Bonding
    1. Ionic
      1. Bonding
        1. When atoms form chemical bonds by transferring electrons, they form ions.
          1. •Atoms that lose electrons become positively charged ions - more protons than electrons
            1. •Atoms that gain electrons become negatively charged ions - fewer protons than electrons
        2. Reactions
          1. Group 1 elements all react with non-metal elements to form ionic compounds, in which the metal ion has a single positive charge.
            1. Group 7 elements react with the alkali metals to form ionic compounds, in which the halide ions have a single negative charge
              1. The reactions between the elements in groups 1 and 7 are all very exothermic. Some are explosive in nature, and they all produce soluble white solids.
          2. Compounds
            1. An ionic compound is a giant structure of ions held together by strong forces of attraction between oppositely charged ions. These ions act in all directions in the lattice, this is called ionic bonding.
              1. In the formula for any ionic compound, the sum of the charges on the ions must be 0.
                1. "An ionic bond is an omnidirectional electrostatic force of attraction between oppositely charged ions"
          3. Covalent Bonding
            1. Metallic Bonding
            2. How structure influences the properties and uses of substances
              1. Atomic Structure, analysis and quantitive chemistry
                1. Rates of Reaction
                  1. Exothermic and Endothermic Reactions
                    1. Acids, Bases and Salts
                      1. Electrolysis
