Patterns of Reactivity
  1. Reactions
    1. Metals will gradually react with he air and water fro the atmosphere.
      1. Copper and gold will not tarnish even after a long time.
        1. Sodium and potassium tarnish so quickly that they needed to be stored into oil.
          1. Sodium and potassium are alkali metals. They are soft and easy to cut.
          2. Water Reactions
            1. Some metals react with cold water to produce hydrogen.
              1. Some metals react more readily with water than others.
              2. Acidic Reactions
                1. Metals react with acids to produce hydrogen and a salt.
                  1. Some metals react more readily with acids than others.
                    1. Some metals do not react with acid.
                    2. Oxygen Reactions
                      1. Metals react with oxygen to form oxides.
                        1. The reactivity series for metals with oxygen is generally similar to tat for water and acids.
                        2. Displacement Reactions.
                          1. In a displacement reaction, a metal displaces a less reactive metal from a solution of one of its salts.
                            1. We can use the order of reactivity of metals to make predictions about other metals that have not been observed.
                            2. Metals
                              1. Metals have a variety of different uses
                              2. Extraction
                                1. The reactivity of a metal affects its uses and the extraction method from is ore.
                                  1. Less reactive metals such as iron are extracted by reactin the ore with carbon. They way iron is extracted rom haematite.
                                    1. Reactive metals such as sodium need t be extracted by electrolysis.
