The Attempt at a Solution
I've tried factorising my k terms and much more faffing about to no avail...help please? :s
Thanks awfully Mapes, but I was already aware that Uranium has 92 protons and 141-6 neutrons, significantly more than Iron. I may be sounding somewhat dim, I'm all too aware, but I was rather hoping there was more to it than that? Or am I just over-complicating this whole business?
