The Reactivity Series and Displacement

To determine whether an element will displace an element in a compound when it reacts with it, chemists use the Reactivity Series to see which element is more reactive

If the element in the compound is more reactive than the element it is reacting with, then it won't be displaced

If the element in the compound is less reactive than the element it is reacting with, then it will be displaced
