That paper wasn't too bad. Thought it would be a lot harder. The third to lat question where you had to fill in the numbers weird. Never seen it in my life.

But of a late reply but are you talking about the alpha/beta equation (can't remember which one) because it's in the syllabus

Yup it was definitely in the syllabus it's when the particle splits from the atom and you have to calculate what the RAM number and proton number is, all you had to do was make it equal to its original total. Hope that helped

I added one more neutron because a neutron was absorbed splitting it into two. So i added the extra neutron and then used that to work it out. Don't think im right though
