Do we need to know that - won't they give you it on the paper if you need it?
Yeah you don't need to remember half lives!

Yeah, you don't need to know half-lives - they give them to you - you just need to know how to work them out. I am so worried about this exam because it is physics and my brain just goes into meltdown with physics even though I have done the modules and I understand them. I have french tomorrow too! WAAAAAA! My two worst subjects in one day!!!!!!!!!!!!!!! Argh!!!!! Tomorrow is going to be a tough day! Good luck everyone!

For those who are doing AQA Physics Modular A, in the specification, it says "suggest why the new model very quickly became widely accepted..." (The model is the one of an atom that Rutherford created after the alpha particle experiment.) Does anyone know why?
because he had the experiment to back up his ideas :smile:
