The Reactivity Series The following table shows the reactivity series of metals and how to remember them using a mnemonic. A more reactive metal donates electrons more readily to form a cation. So in the process of oxidation it reduces the other element so it is called reducing agent. Reactivity of metals (overview) Our mission is to provide a free, world-class education to anyone, anywhere. Reactivity Series of Metals Match correctly the chemical reactions with the expected results. Then, determine the suitable extraction method for different metals. We can see the loss of electrons in the oxidation half-equation above. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. This sweeping statement is a gross generalisation. Reactivity Series of Metals pupil worksheet2. It is more comfortable being a pure element, somewhat retaining its valence electrons. A less reactive metal is a hoarder — it would rather have its valence electrons. Activity Series The relative reactivity of metals can be used to organize them into an activity series. For example, because aluminium is more reactive than iron, it can displace iron from iron(III) oxide. They easily take part in chemical reactions to make new substances. This sparks a spectacular reaction that is highly exothermic, forming molten iron and aluminium oxide. The ideas behind the 'Reactivity Series of Metals' is introduced and what happens to a metal atom when it reacts. The unreactive metals do not react at all, even when we use strong acid or high temperature. They have the greatest tendency to lose electrons to form cations. Once organized, an activity series helps us to predict if a reaction will occur when a piece of elemental metal is placed in water, an acid solution, or a solution containing the ion of another metal.
