The reactivity series lists metals from the most reactive to the least reactive. A metal can displace a less reactive metal from its compounds. This is useful for extracting metals from their oxides.
Which of these three metals is the most reactive: potassium, iron or gold?
Which of these three metals is the least reactive: iron, copper or platinum?

A burning splint goes out
A burning splint burns more brightly
A burning splint makes a squeaky pop sound
What are the products when calcium reacts with nitric acid?
Calcium chloride and hydrogen
Calcium oxide and carbon dioxide
Calcium nitrate and hydrogen
What are the products when magnesium reacts with sulfuric acid?
Magnesium sulfate and hydrogen
