The reactivity series is a list of chemical elements, mostly metals, arranged in order of their decreasing chemical reactivity from most to least reactive. This order is based on how easily an element loses electrons to form a positive ion, with highly reactive elements losing electrons readily and reacting more vigorously. The series predicts how metals will react with substances like water and acids and can be used to understand displacement reactions and extract metals from their ores. How it
