- In this section, we describe the relationship between mand energy in nuclear reactions and show how the seemingly small changes in .Nuclear reactions may be shown in a form similar to chemical equations, for which In order to solve, we find the difference between the atomic m.es and atomic Calculate the mdefect and nuclear binding energy of an atom .Section 10.1: To describe the half-life of nuclei and radio-carbon dating. Section 10.2: To further explore the relationship between mand energy.. - 6 In a nuclear reaction, mis not strictly conserved. Some of the mis converted into energy,according to the equation E = mc2 and the .
