Question 1 · 1 mark · Difficulty 1/3

A student in Trinidad placed iron nails, zinc strips, and copper wire in separate beakers of dilute hydrochloric acid and observed the rate of bubble formation. Which metal would produce bubbles most rapidly?

  1. Iron
  2. Zinc
  3. Copper
  4. All three would react at the same rate
Show answer & explanation
✓ Answer: BZinc
Award 1 mark for identifying zinc as the most reactive metal among the three. Zinc is higher in the reactivity series than iron, so it reacts more vigorously with dilute acid. A is incorrect — iron reacts but more slowly than zinc. C is incorrect — copper is below hydrogen in the reactivity series and does not react with dilute acids. D is incorrect — reactivity varies according to position in the reactivity series.
Question 2 · 1 mark · Difficulty 1/3

Which property is common to ALL metals?

  1. They are magnetic
  2. They conduct electricity
  3. They react with dilute acids
  4. They have high melting points
Show answer & explanation
✓ Answer: BThey conduct electricity
Award 1 mark for identifying electrical conductivity as a property shared by all metals due to the presence of delocalised electrons. A is incorrect — only iron, cobalt, and nickel are magnetic. C is incorrect — unreactive metals like copper and gold do not react with dilute acids. D is incorrect — mercury has a low melting point (-39°C).

CXC CSEC Integrated Science: Metals: Properties, Reactivity Series and Corrosion FAQ

How many CXC CSEC Integrated Science questions on Metals: Properties, Reactivity Series and Corrosion are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Metals: Properties, Reactivity Series and Corrosion for CXC CSEC Integrated Science, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CXC paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CXC CSEC students preparing for Integrated Science?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Metals: Properties, Reactivity Series and Corrosion practice with other Integrated Science topics or even switch to a totally different CXC subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Metals: Properties, Reactivity Series and Corrosion questions aligned to the official CXC CSEC Integrated Science syllabus?
Every question is written against the published CXC CSEC Integrated Science specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CXC.
How is Metals: Properties, Reactivity Series and Corrosion typically tested on CXC CSEC Integrated Science papers?
Metals: Properties, Reactivity Series and Corrosion appears across multiple question types on real CXC CSEC Integrated Science papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
