- A fluorine - 18 nucleus can capture proton producing a neon - 19 nucleus as the product. The mass defect of fluorine - 18 and neon - 19 are 0.14712 u and 0.15398 u respectively. What is the energy change associated with this reaction?
- E = mc^2
I got 6.5 MeV but I don't understand how to determine whether the energy is released or absorbed. My guess: the energy is absorbed because mass defect of neon is bigger?
