Q: How do I try a free AQA 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 AQA 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 AQA 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 AQA GCSE syllabus?

Every question is written against the published AQA 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 AQA past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Uranium has two isotopes: U-235 and U-238. Compared to U-235, U-238 has:

Accepted Answer

B) The same protons and more neutrons — Both isotopes have the same atomic number (92 protons) because they are both uranium. U-238 has 238 − 92 = 146 neutrons, while U-235 has 235 − 92 = 143 neutrons, giving U-238 three more neutrons.
