Question 1 · 1 mark · Difficulty 1/3

Which type of bond is formed when electrons are transferred from one atom to another?

  1. Covalent bond
  2. Ionic bond
  3. Metallic bond
  4. Hydrogen bond
Show answer & explanation
✓ Answer: BIonic bond
Award 1 mark for identifying ionic bonding as the result of electron transfer. A is incorrect — covalent bonds involve sharing of electrons. C is incorrect — metallic bonds involve a 'sea' of delocalised electrons. D is incorrect — hydrogen bonds are weak intermolecular forces, not formed by electron transfer.
Question 2 · 1 mark · Difficulty 2/3

A student in a Trinidad laboratory heated sodium chloride and sugar separately. She observed that sodium chloride melted at a much higher temperature than sugar. Which statement best explains this observation?

  1. Sugar has stronger bonds than sodium chloride
  2. Sodium chloride contains ionic bonds which require more energy to break
  3. Sugar contains ionic bonds while sodium chloride contains covalent bonds
  4. Sodium chloride has a lower molecular mass than sugar
Show answer & explanation
✓ Answer: BSodium chloride contains ionic bonds which require more energy to break
Award 1 mark for linking ionic bonding to high melting point. A is incorrect — ionic bonds in NaCl are stronger than covalent bonds in sugar. C is incorrect — it reverses the bond types. D is incorrect — molecular mass does not directly determine melting point in this comparison.

CXC CSEC Integrated Science: Chemical Bonding FAQ

How many CXC CSEC Integrated Science questions on Chemical Bonding are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Chemical Bonding 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 Chemical Bonding 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 Chemical Bonding 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 Chemical Bonding typically tested on CXC CSEC Integrated Science papers?
Chemical Bonding 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.
