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

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.
