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.

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.
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.
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.
