Metals and reactivity
14 review questions with answers for Metals and reactivity. Read them here, or play the set as a class game on the projector. Free to host, and students join with a code.

What this set covers
Where metals sit in the reactivity series and what that means for extraction and use. The set covers ores, carbon reduction versus electrolysis, rusting and galvanising, displacement in solutions, reactions with water and acid, and alloys.
- Common mix-up
- Students often mix up oxidation and reduction in extraction: removing oxygen from a metal oxide is reduction, and the reactivity series decides whether carbon can do it or electrolysis is needed.
- Review tip
- Write the metals from these questions in reactivity order, then use the order to predict whether zinc, iron and silver would displace copper from copper(II) sulfate.

Play it as a class game
Play this set opens it in splycr, where you can host it for your class straight away. Hosting needs no account: put the room code on the projector, and students join from a phone with the code and their first name. Each question plays as multiple choice, and the three wrong options were written for that question.
