Question 1 · 1 mark · Difficulty 1/3

A student at a secondary school in Barbados was investigating the structure of atoms. She learned that atoms contain three types of subatomic particles. Which of the following particles has NO electrical charge?

  1. Proton
  2. Neutron
  3. Electron
  4. Ion
Show answer & explanation
✓ Answer: BNeutron
Award 1 mark for identifying neutron as having no charge. A is incorrect because protons carry a positive charge. C is incorrect because electrons carry a negative charge. D is incorrect because an ion is a charged atom, not a subatomic particle.
Question 2 · 1 mark · Difficulty 1/3

Which scientist proposed that electrons orbit the nucleus in specific energy levels or shells?

  1. John Dalton
  2. J.J. Thomson
  3. Ernest Rutherford
  4. Niels Bohr
Show answer & explanation
✓ Answer: DNiels Bohr
Award 1 mark for Bohr. Bohr proposed in 1913 that electrons occupy fixed energy levels around the nucleus. A is incorrect because Dalton proposed atoms as solid spheres. B is incorrect because Thomson proposed the plum pudding model. C is incorrect because Rutherford proposed the nuclear model but did not specify electron shells.

CXC CSEC Physics: The Structure of the Atom and Atomic Models FAQ

How many CXC CSEC Physics questions on The Structure of the Atom and Atomic Models are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on The Structure of the Atom and Atomic Models for CXC CSEC 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 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 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 The Structure of the Atom and Atomic Models practice with other Physics 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 The Structure of the Atom and Atomic Models questions aligned to the official CXC CSEC Physics syllabus?
Every question is written against the published CXC CSEC Physics 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 The Structure of the Atom and Atomic Models typically tested on CXC CSEC Physics papers?
The Structure of the Atom and Atomic Models appears across multiple question types on real CXC CSEC 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.
