Why do ionic compounds have high melting points?

Q: How do I try a free Edexcel Chemistry question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live Edexcel GCSE Chemistry bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for Edexcel Chemistry students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Chemistry questions aligned to the Edexcel GCSE syllabus?

Every question is written against the published Edexcel GCSE Chemistry syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real Edexcel past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Why do ionic compounds have high melting points?

Accepted Answer

Strong electrostatic forces between many ions in a giant lattice require lots of energy to overcome — Ionic compounds form giant lattices with strong electrostatic attractions throughout. Lots of energy needed to break these forces.

Answer

They are heavy

Answer

They are covalent

Answer

They contain free electrons
