Writing Nuclear Equations The key to balancing nuclear reactions is to treat the balance of the mass numbers and atomic numbers separately. Step 1. Determine the mass number of the missing nuclide by difference, assuming the sum of the mass numbers of the products must equal the sum of the mass numbers of the reactants. Remember to account for multiple particles of the same type by multiplying by the stoichiometric coefficient. Step 2. Determine the atomic number of the missing nuclide by difference, assuming the sum of the atomic numbers of the products must equal the sum of the atomic numbers of the reactants. Remember to account for multiple particles of the same type by multiplying by the stoichiometric coefficient. If a free electron is present as a reactant or product in a nuclear reaction, it has an atomic number of -1. A positron has an atomic number of +1. Step 3. Use the atomic number to obtain the one- or two-letter atomic symbol from the periodic table. The overall symbol for the nuclide is written by superscripting the mass number and subscripting the atomic number. These are entered to the left of the one- or two-letter atomic symbol. Step 4. A nuclear reaction which two lighter nuclides join (fuse) to form a larger (heavier) nuclide is called a fusion reaction. A nuclear fission reaction occurs when a heavier nuclide splits into nuclides of lower atomic number. Complete the following nuclear bombardment equation by filling in the nuclear symbol for the missing species. 2351T - in - *Sr + 2 on Is this a nuclear fusion reaction or a nuclear fission reaction? Submit The key to balancing nuclear reactions is to treat the balance of the mass numbers and atomic numbers separately. The element symbol can be determined last. What is the mass number of the missing product? mass number = Submit What is the atomic number of the missing product? atomic number = Submit
