Question 1 · 1 mark · Difficulty 1/3

Which of the following diagrams best represents the structure of sodium chloride?

  1. A giant covalent lattice with shared electrons
  2. A regular arrangement of oppositely charged ions
  3. Simple molecules held together by weak forces
  4. A network of atoms sharing pairs of electrons
Show answer & explanation
✓ Answer: BA regular arrangement of oppositely charged ions
Award 1 mark for identifying the regular arrangement of oppositely charged ions. A is incorrect because sodium chloride has ionic bonding, not covalent bonding. C is incorrect because ionic compounds are not molecular. D describes covalent bonding, not ionic bonding.
Question 2 · 1 mark · Difficulty 1/3

Which electron configuration represents a chloride ion, Cl⁻?

  1. 2,8,7
  2. 2,8,8
  3. 2,8,6
  4. 2,7
Show answer & explanation
✓ Answer: B2,8,8
Award 1 mark for 2,8,8. Chlorine has electronic configuration 2,8,7 and gains one electron to form Cl⁻ with configuration 2,8,8. A is incorrect as this is the configuration of a chlorine atom, not the ion. C is incorrect as this would be an O atom. D is incorrect as this is not a valid configuration for chlorine.

CIE IGCSE Chemistry: Ions and ionic bonding FAQ

How many CIE IGCSE Chemistry questions on Ions and ionic bonding are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Ions and ionic bonding 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 Ions and ionic bonding 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 Ions and ionic bonding 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 Ions and ionic bonding typically tested on CIE IGCSE Chemistry papers?
Ions and ionic bonding 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.
