The reactivity seriesThe reactivity series is the list of metals placed in order of their reactivity. The reactivity series can be used to make predictions about the reactions of metals. One way to remember this order is to learn this silly sentence:

Displacement

During a displacement reaction the metal in a compound is replaced with a more reactive metal to form a new compound. potassium

A Model of a displacement

Like people compounds find some partners more attractive than others, and will ‘ditch’ one metal for another.

Another Model

In this model the non-metal part of the compound is like a footballer leaving his club for one higher up the league.

Displacement reactions – examples

The reactivity series can be used to predict if a metal will react with a metal compound.

Will magnesium react with copper chloride?

Will silver react with magnesium chloride?

Magnesium is a more reactive metal than copper, so magnesium displaces the copper from its compound.

Silver is a less reactive metal than magnesium, so silver does not displace the magnesium from its compound.
