WebAug 15, 2024 · Explaining the increase in reactivity down the group The reactions proceed faster as the energy needed to form positive ions falls. This is in part due to a decrease in ionization energy down the group, and in part to a decrease in atomization energy reflecting weaker metallic bonds from lithium to cesium. WebLesson 1 is a series of test tube experiments in which each working group establishes as a common feature that hydrogen is given off as metals react with an acid – if the metal reacts at all. This should take around 40 minutes, and most classes should be …

9: Single Replacement Reactions and Batteries (Experiment)

WebThe video offers three experiments that investigate the relative reactivity of metals. The first explores the reactions of the alkali metals in water and is a teacher demonstration. Exothermic reactions of metals and acid and metal displacement reactions are experiments that learners can carry out themselves. These investigations Learners could repeat the displacement reactions experiment and include the unknown metal and metal sulfate. Tin will be more reactive than copper but less reactive than iron.
