Atomic structure trial videos
Learn subatomic particles, proton number, nucleon number, electronic configuration and isotopes across two complete lessons from the IGCSE Chemistry 2026–2027 course.
Key takeaways
Searches the words spoken in this lesson — e.g. “phosphoric” or “pH scale”. Punctuation doesn’t matter.
Tip: pause after each worked example and write the proton, neutron and electron counts or electronic configuration before revealing the explanation.

Try this IGCSE Chemistry online course free — no card needed
You can try this Cambridge IGCSE Chemistry online course free, for syllabus 0620 — the real atomic structure lesson, not a preview. You get two complete videos, the trial notes flipbook, a 10-question quiz, a live Paper 2 trial and a 15-page Paper 4 pack, with no sign-up and no card needed. Everything opens straight away, so you can judge the teaching before you spend anything.
Who is this for?
This trial is built for students sitting any exam session in the coming two years, and for anyone who wants to see how IGCSE Chemistry is actually taught before committing. It suits students revising alongside school, students self-studying without a teacher, homeschooling families who need a complete recorded course, and parents comparing online tutors who would rather watch a full lesson than read a sales page. Because every lesson is recorded, you can pause, repeat a difficult explanation and come back to it the night before a test.
How to get the most out of this free lesson
Watch the lesson first without taking notes, then run the quiz cold — the score tells you what actually stuck rather than what felt familiar. After that, open the worked past-paper questions and cover the answer before you read it. Marks in IGCSE Chemistry are usually lost in the wording, not the science, so comparing your phrasing against a full model answer is the fastest way to gain them.
What the full course includes
- Recorded lectures covering every topic in the specification, taught in the same style as this trial
- The complete notes library, written to be revised from rather than skimmed
- Solved past papers with full written answers and video explanations, classified by topic and available as full papers
- Topic quizzes and flashcards that mark every answer instantly, so you find weak spots before the examiner does
- Access on phone, tablet and laptop — pick up on any device where you left off
For the full syllabus breakdown, the topic list and the notes library, see the IGCSE Chemistry course page on chem-bio.info. It lists the topics, the exam structure and everything that comes with the paid course, so you can compare it against the free lesson you have just tried.
