7.17 and 7.18 starter 13 January 2012 14:02 A fuel that doesn’t burn. What is it? Answers
· Uranium. When Uranium atoms split into two (fission) they release energy which can be captured in a nuclear power station. This is a nuclear reaction and is fundamentally different to burning (combustion is a chemical reaction) 7.17 and 7.18 starter 2 13 January 2012 14:02 How many protons and neutrons are there in
· 23592U?
· 23692U? Answers
· 23592U = 92 protons; 143 neutrons. This radioisotope of Uranium is commonly used as a fuel for nuclear power stations
· 23692U = 92 protons; 144 neutrons This radioisotope of Uranium is highly unstable and is artificially created in nuclear power stations where it undergoes fission 7.17 and 7.18 12 January 2012 10:32
· 7.17 understand that a nucleus of U-235 can be split (the process of fission) by collision with a neutron, and that this process releases energy in the form of kinetic energy of the fission products
· 7.18 recall that the fission of U-235 produces two daughter nuclei and a small number of neutrons
