Epic and Wholesome Mnemonic. It can be used to predict the products in similar reactions involving a different metal. Learn the reactivity series of metal through this simple yet effective mnemonic. . This shows that the metal is more reactive than hydrogen. A more reactive metal will displace a less reactive metal from solution. Therefore hydrogen sits above copper in the reactivity series. If we put the metals in order of their reactivity, from the most reactive down to the least reactive, we get a list called the reactivity series. Magnesium and zinc are often used as sacrificial metals. The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities. Interestingly, carbon can behave like a metal. It is used to determine the products of single displacement reactions, whereby metal A will replace another metal B in a solution if A is higher in the series. This is useful for extracting metals from their oxides. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their "reactivity" from highest to lowest. Use the reactivity series to explain the displacement of metals. Reactivity of metals (overview) Up Next. The reactivity series arranges metals from the most reactive to the least. Epic and Wholesome Mnemonic. Metals and alloys: Materials that changed history. They easily take part in chemical reactions to make new substances. Info. Some react explosively, some moderately, and others not at all. Metals The reactivity series lists metals from the most reactive to the least reactive. Our tips from experts and exam survivors will help you through. Lead in Group IV is also moderately reactive. If you're behind a web filter, please make sure that the domains *.kastatic.org and *.kasandbox.org are unblocked. This happens because iron is more reactive than copper. The reactivity series lists metals from the most reactive to the least reactive. Moderately reactive metals require a higher temperature to react with water. How does the reactivity series of metal help? Highly Reactive Group I and II Metals Group I alkali metals and Group II alkaline earth metals are the most reactive. If you want to learn the reactivity series, you could try making up a mnemonic or silly sentence to help. At the same time, we form iron(II) sulfate, whereby iron has taken the place of copper. The reactivity series allows us to predict how metals will react. This sweeping statement is a gross generalisation. It is used to summarize information about the reactions of metals with acids and water, single displacement reactions and the extraction of metals from their ores. Metal activity or reactivity series finds its utility in the study of displacement reactions. A reactivity series lists metals in order of how reactive they are.

By using the reactivity series of metals, one can predict the products of displacement reaction. We illustrate the gain of electrons in the reduction half-equation above. 3 Reactions of metals with water When a metal reacts with water hydrogen is always given off. For example, platinum does not react with oxygen in the air, even if it is heated in a Bunsen burner flame. A metal can displace a less reactive metal from its compounds. Magnesium is very reactive. Metals generally react with acids. These metals are … This is what happens when a metal rusts. We will be using mnemonics for creating easy way of memorizing the topic. Its reactivity is slightly above that of zinc. This means they do not easily take part in chemical reactions. And the least reactive metals we need to know are copper, silver, and gold. Here's one: "Pond slime can make a zoo interesting - the long crinkly sort goes purple.". Metal + oxygen → metal oxide (a) Metal undergoes oxidation to form positive ions. One of the common compounds formed by metals is metal oxide. Reactive metals can also displace less reactive ones from solid metal oxides. Metalworkers exploit this displacement reaction to extract less reactive metals from their oxides. For example, platinum does not react with oxygen in the air, even if it is heated in a Bunsen burner flame. For example, because aluminium is more reactive than iron, it can displace iron from iron(III) oxide. Reactivity Series of Metals pupil worksheet. It ignites when heated and burns with a brilliant white flame, Other metals may be more reactive than magnesium, or in between magnesium and platinum. Read about our approach to external linking. 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. Memorise the reactivity series of metals without memorising. Oxidation reactions are those reactions in which an element or ion loses one electron or more than one electrons. Such element is called a reducing agent as to when it loses one or more electron which will be accepted by another element. Metals, Reactivity and King Canute. This means that it can displace zinc and other less reactive metals from their oxides. The trio sit in the same column within the transition metal hood. 4. The reactivity series allows us to predict how metals will react. Metal displacement occurs when a more reactive metal forms a cation and displaces a less reactive metal from its compounds. For the four metals we need to know, those from Group I are more reactive than those from Group II. Title: Metals reactivity series 1 Reactivity series 2 Reactions of metals with oxygen When a metal reacts with oxygen it will form a METAL OXIDE. This prevents iron from losing its electrons and becoming oxidised In the process of the losing electron that element gets oxidized. Thus, the least reactive metal is placed at the bottom while the most reactive metal is placed at the top of the series. The series which arranges metals in the decreasing order of reactivity is known as the reactivity series. Reactivity series.
