"WebThe nuclear reaction can be written as: 12 25 Mg + 2 4 He 1 1 H + Z A X. where A is the mass number and Z is the atomic number of the new nuclide, X. Because the sum of the mass numbers of the reactants must equal the sum of the mass numbers of the products: 25 + 4 = A + 1, or A = 28. Similarly, the charges must balance, so: " - How do large groups of nuclei behave
