In chemistry, the reactivity series is a series of metals, in order of reactivity from highest to lowest. :In chemistry, the reactivity series is a series of metals, in order of reactivity from highest to lowest.
Slide 8:A metal can replace metals listed below it in the activity series, but not above. For example, sodium (acting as an oxidising agent) is highly reactive and thus able to displace hydrogen from water:
2 Na (s) + 2 H2O (l) → 2 NaOH (aq) + H2 (g)
