this is the answer
hope its helpful
Answer
The reactivity series of metals, also known as the activity series, refers to the arrangement of metals in the descending order of their reactivities.

Important uses of Reactivity Series
Apart from providing insight into the properties and reactivities of the metals, the reactivity series has several other important applications.
For example, the outcome of the reactions between metals and water, metals and acids, and single displacement reactions between metals can be predicted with the help of the activity series.
