Question 1 · 1 mark · Difficulty 1/3

An atom has 17 protons, 18 neutrons, and 17 electrons. What is the mass number of this atom?

  1. 52
  2. 35
  3. 18
  4. 17
Show answer & explanation
✓ Answer: B35
Mass number = number of protons + number of neutrons = 17 + 18 = 35. Option A is just the proton number (atomic number). Option B is just the neutron number. Option D incorrectly adds all three subatomic particle counts together.
Question 2 · 1 mark · Difficulty 1/3

Which of the following correctly describes the charge and location of a neutron?

  1. Charge of −1, found outside the nucleus
  2. Charge of 0, found in the nucleus
  3. Charge of +1, found in the nucleus
  4. Charge of 0, found outside the nucleus
Show answer & explanation
✓ Answer: BCharge of 0, found in the nucleus
Neutrons have no electrical charge (relative charge = 0) and are located in the nucleus alongside protons. Option A describes the proton incorrectly labelled as a neutron. Option B describes the electron. Option D correctly states charge of 0 but places the neutron outside the nucleus, which is incorrect.

CIE IGCSE Chemistry: Atomic structure and the periodic table FAQ

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