1. The problem statement, all variables and given/known data What is the equation for the reaction of a alpha particle and beryllium with production of one neutron 2. Relevant equations Use an a chem equation 3. The attempt at a solution The masses are 4 + 9 = 1 + x, so x = 12. The atomic numbers (protons) are 2 + 4 = 0 + x, so x is 6 Therefore a neutron and Carbon 12 is produced. Is this correct????
