Reactivity Series

Quick Reference
Also Known AsActivity series, electrochemical series (partial), metal activity series

What is Reactivity Series?

A list of metals arranged in order of decreasing reactivity, from most reactive (potassium, sodium) to least reactive (gold, platinum). A more reactive metal can displace a less reactive metal from its salts in solution. Also called the activity series or electrochemical series.

Properties & Characteristics

The reactivity series is an ordered list of metals arranged by their tendency to react or lose electrons (be oxidised). Metals higher in the series displace those lower from salt solutions. It correlates with standard electrode potentials. The series guides predictions of displacement reactions and corrosion behaviour.

Uses & Applications

The reactivity series is used to predict which metals can displace others from solutions, guiding extraction processes like thermite reduction. It informs selection of materials for construction to minimise galvanic corrosion. It is used in electrochemical cells and battery design.

Safety Information

Highly reactive metals such as potassium and sodium react vigorously with water, producing hydrogen gas and heat. These metals must be stored under inert conditions and handled with extreme care.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
