40 revision flashcards AQA physics Atomic structure P4 differentiated GCSE

This is a set of flashcards created for the atomic structure unit for AQA GCSE physics. The flashcards are double-sided (flip on long edge), so the answer is on the reverse of each card, and are colour-coded with blue cards being the easiest, green mid-difficulty and red the most challenging.
With my lowest ability groups I ask them to learn the blue cards as a minimum. My higher ability groups learn the blue cards first, then the green and red cards.
