Order of Reactivity
What is Order of Reactivity?
An arrangement of metals from most reactive to least reactive, worked out from experimental results rather than recalled. Each result gives one comparison between two things; chaining the comparisons together gives the order, and any pair the results never compare stays undetermined.
This definition is part of the Metals chapter in Cambridge IGCSE Chemistry.
