A reactivity series is used to rank the chemical reactivity of a group of metals from most reactive to least reactive.
Explanation:
The reactivity series is a series of metal elements, and sometimes carbon and hydrogen, that is arranged according to their reactivity. A reactivity series is typically a vertically presented model with the most-reactive element placed at the top of the series and the least-reactive element placed at the bottom.
The reactivity series of metals is a chart listing metals in order of decreasing reactivity. In general, the more reactive a metal is: the more vigorously it reacts with other substances. the more easily it loses electrons to form positive ions (cations)
