Grades 9–10 · Chemistry
This quiz helps revise “Atomic structure” in Chemistry for grades 9–10. It has 25 questions in five categories: Inside an Atom, Atomic Numbers, Energy Levels, Charged Atoms, How We Found Out. Questions get harder as the points go up, from 100 to 500.
The 100- and 200-point questions are open here. The rest show only their first words, and there are no answers: all of that is in the game itself.
