Reactivity series

In this Class 10 Science topic from the chapter Metals and Non-metals, students learn how metals are arranged in the reactivity series according to their tendency to lose electrons and form compounds. They compare the reactions of metals with water, acids and oxygen, and use the series to predict displacement reactions, such as when a more reactive metal displaces a less reactive metal from its salt solution. The topic also connects reactivity with metal extraction and everyday observations.
