In an Activity Series we compare a list of elements to one another to determine their reactivity towards oxidation. 

Activity Series Chart 

Concept #1: Activity Series

Using an Activity Series Chart allows you to determine if a metal is reactive enough to displace hydrogen from a compound. 

Example #1: Activity Series

An Activity Series Chart can even be used to determine if a metal is reactive enough to displace another metal from a compound. 

Example #2: Activity Series

For halogens, Group 7A elements, the trend in reactivity follows a predictable pattern. 

Example #3: Activity Series
