Go to Metal ExtractionWhat is Reactivity Series?
The reactivity series is a list of metals arranged in order of their reactivity, from most reactive to least reactive. A metal's position in the series determines how readily it loses electrons to form positive ions. A more reactive metal can displace a less reactive metal from its compound.
Board notes: The reactivity series is a key concept for all exam boards. You need to know the order of reactivity for common metals and be able to predict the products of displacement reactions. Its link to metal extraction is also very important.
Step-by-step explanationWorked example
If you place a piece of iron in a solution of copper(II) sulfate, the iron is more reactive than the copper. The iron will displace the copper, forming iron(II) sulfate and solid copper: Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s).
Mini lesson for Reactivity Series
1. Understand the core idea
The reactivity series is a list of metals arranged in order of their reactivity, from most reactive to least reactive. A metal's position in the series determines how readily it loses electrons to form positive ions.
Can you explain Reactivity Series without copying the notes?
2. Turn it into marks
If you place a piece of iron in a solution of copper(II) sulfate, the iron is more reactive than the copper. The iron will displace the copper, forming iron(II) sulfate and solid copper: Fe(s) + CuSO₄(aq) → FeSO₄(aq) + Cu(s).
Underline the method, evidence, or command-word move that would earn credit in GCSE Chemical Changes.
3. Fix the likely mark leak
Watch for this mistake: Memorising the series in the wrong order. A common mnemonic is 'Please Stop Calling Me A Cute Zebra, I Like Her Call, Smart Guy!' (Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Lead, Hydrogen, Copper, Silver, Gold).

Reactivity Series practice questions
These are original StudyVector questions for revision practice. They are not official exam-board questions.
Question 1
In one GCSE sentence, explain what Reactivity Series is testing.
Answer: The reactivity series is a list of metals arranged in order of their reactivity, from most reactive to least reactive. A metal's position in the series determines how readily it loses electrons to form positive ions.
Mark focus: Precise definition and topic focus.
Question 2
A Reactivity Series question uses an unfamiliar context. What should the answer do before adding detail?
Answer: It should name the process, variable, equation, particle model, or evidence being tested, then explain the result using precise scientific vocabulary.
Mark focus: Method selection and command-word control.
Question 3
A student makes this mistake: "Memorising the series in the wrong order. A common mnemonic is 'Please Stop Calling Me A Cute Zebra, I Like Her Call, Smart Guy!' (Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Lead, Hydrogen, Copper, Silver, Gold)." What should their next repair task be?
Answer: Do one Reactivity Series question and review the mistake type.
Mark focus: Error correction and next-step practice.

Core idea
What is the main idea in Reactivity Series?
The reactivity series is a list of metals arranged in order of their reactivity, from most reactive to least reactive. A metal's position in the series determines how readily it loses electrons to form positive ions.
Common mistake
What mistake should you avoid in Reactivity Series?
Memorising the series in the wrong order. A common mnemonic is 'Please Stop Calling Me A Cute Zebra, I Like Her Call, Smart Guy!
Practice
What is one useful practice task for Reactivity Series?
Answer one Reactivity Series question and review the mistake type.
Exam board
How should you use board notes for Reactivity Series?
The reactivity series is a key concept for all exam boards. You need to know the order of reactivity for common metals and be able to predict the products of displacement reactions.
Common mistakes
- 1Memorising the series in the wrong order. A common mnemonic is 'Please Stop Calling Me A Cute Zebra, I Like Her Call, Smart Guy!' (Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Lead, Hydrogen, Copper, Silver, Gold).
- 2Forgetting that carbon and hydrogen are included in the series for comparison, even though they are non-metals.
- 3Confusing displacement reactions with other reaction types. A displacement reaction is specifically when a more reactive element takes the place of a less reactive element in a compound.

Frequently asked questions
How can you determine the reactivity of two metals?
You can react each metal with water, acid, or a solution containing the ions of the other metal. The metal that reacts more vigorously or displaces the other is the more reactive one.
What is the connection between reactivity and extraction?
The position of a metal in the reactivity series determines how it is extracted from its ore. Metals more reactive than carbon must be extracted by electrolysis, while less reactive metals can be extracted by reduction with carbon.
