Compound.
No. In a displacement reaction, that is exactly what happens. If an element low down in the reactivity series is in a compound, and you add an element that is higher placed in the reactivity series. The more reactive element will displace the less reactive element in the compound.Example:Copper Sulphate - Copper is low in the reactivity series and is in a compoundSodium + Copper Sulphate - Sodium is higher in the reactivity series than copper, and is in it's pure elemental form.Copper + Sodium Sulphate - The Sodium that is higher in the reactivity series has switched places with the Copper, which is lower in the reactivity series.FULL EQUATION:Sodium + Copper Sulphate --> Copper + Sodium Sulphate
