Question 1 · 1 mark · Difficulty 1/3

Which particle is emitted during alpha decay?

  1. A helium-4 nucleus
  2. A high-energy electron
  3. A high-energy photon
  4. A neutron
Show answer & explanation
✓ Answer: AA helium-4 nucleus
An alpha particle consists of 2 protons and 2 neutrons, identical to a helium-4 nucleus. Alpha decay reduces the atomic number by 2 and the mass number by 4. It is not an electron, photon, or neutron.
Question 2 · 1 mark · Difficulty 2/3

Uranium-238 undergoes alpha decay. What are the mass number and atomic number of the daughter nucleus?

  1. Mass number 234, atomic number 90
  2. Mass number 236, atomic number 90
  3. Mass number 234, atomic number 92
  4. Mass number 236, atomic number 92
Show answer & explanation
✓ Answer: AMass number 234, atomic number 90
Alpha decay removes 2 protons and 2 neutrons. Uranium has atomic number 92 and mass number 238, so the daughter has mass number 238 − 4 = 234 and atomic number 92 − 2 = 90, which is thorium-234.

AQA GCSE Physics: Nuclear equations and decay products FAQ

How many AQA GCSE Physics questions on Nuclear equations and decay products are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Nuclear equations and decay products for AQA GCSE Physics, 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 AQA 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 AQA GCSE students preparing for Physics?
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 Nuclear equations and decay products practice with other Physics topics or even switch to a totally different AQA 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 Nuclear equations and decay products questions aligned to the official AQA GCSE Physics syllabus?
Every question is written against the published AQA GCSE Physics specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real AQA 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 AQA.
How is Nuclear equations and decay products typically tested on AQA GCSE Physics papers?
Nuclear equations and decay products appears across multiple question types on real AQA GCSE Physics 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.
