It is possible to predict the reaction of metals with acids by looking at the reactivity series and let us learn how. Therefore, they are listed at the bottom of the table. As you can see from the table, metals such as gold and platinum do not form oxides easily when exposed to air, which means they are unreactive. This is exactly what has been depicted in the reaction series. Some metals are highly reactive while there are others that show low reactivity. But interestingly, not all the metals react with atmospheric oxygen at the same level. When metals react with atmosphere oxygen they form metal oxides. One of the salient characteristics of metals as we all already know, is that they lose electrons and form cations. Reaction of Metals with Atmospheric Oxygen But there is also another important lesson that we can learn from the reactivity series, which is understanding the reaction between metals with atmospheric oxygen, water and acids. It is true that the reactivity series gives us an insight into the chemical reactivity of the metals and a comparison between them. Metals as we go down the reactivity series have less electron-donating ability.It requires greater energy to isolate metals mentioned at the top of the list, from their ores and other compounds.Metals whose names are mentioned at the top of the table can displace those that are below their salt solutions.As we travel down the reactivity series, the corroding property reduces and so do their electropositivity.The metals at the top of the reactivity series like Potassium, Sodium and Lithium can get easily oxidised, which means they can corrode easily.Here are some of the most important chemical properties of metals that could be inferred from the reactivity series. Understanding the Chemical Properties of Metals Metals from 18-25 : These are highly unreactive metals.Hydrogen is included in the list for the sake of comparison.What Can We Understand From Reactivity Series of Metals However, most of the commonly used metals are included in the list that is given below. It is not practical to list all the 90+ metals in the reactivity series. On the same note, as Platinum is the least reactive metal, it is seen at the bottom of the list. As alkali metals are the most reactive metals, you will find them at the top of the list. This means, metals that are highly reactive appear at the top of the reactivity series followed by metals with lower reactivities. The reactivity series of metals, sometimes called the activity series of metals, is the listing of metals in a tabular form in the descending order of their reactivity.
