Differentiated atoms and ions worksheet - used during lock down

I made this for Yr 9 during lock down, for students working from phones. Change it to pdf to ensure it’s accessible for all phones. If students don’t have access to printers or equipment, they can match numbers and letters so they don’t have to write everything out. I made a series of these and most 9’s did them.
Part 1 and 2 are low demand, part 3 is a medium True / False and part 4 a challenging True / False.
I took Part 5 from a worksheet I’ve had hanging around for years. I am unable to reference the author - I don’t think it was TES. If it is anyone from TES, I’ll amend and reference (or of course remove if requested).
