  1. Nuclear Equations

  2. For example, the nuclide symbol for uranium-238 is Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. www.assignmentpoint.com

  3. Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • The radioactive decay of by alpha-particle emission (loss of a nucleus) is written www.assignmentpoint.com

  4. Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • Reactant and product nuclei are represented in nuclear equations by their nuclide symbol. www.assignmentpoint.com

  5. Proton or Neutron Electron or Positron or Gamma photon Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • Other particles are given the following symbols. www.assignmentpoint.com

  6. Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • The total charge is conserved during a nuclear reaction. • This means that the sum of the subscripts for the products must equal the sum of the subscripts for the reactants. www.assignmentpoint.com

  7. Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • The total number of nucleons is also conserved during a nuclear reaction. • This means that the sum of the superscripts for the products must equal the sum of the superscripts for the reactants. www.assignmentpoint.com

  8. Nuclear Equations • A nuclear equation is a symbolic representation of a nuclear reaction using nuclide symbols. • Note that if all reactants and products but one are known in a nuclear equation, the identity of the missing nucleus (or particle) is easily obtained. • This is illustrated in the next example. www.assignmentpoint.com

  9. The nuclear equation is • From the superscripts, you can write A Problem To Consider • Technetium-99 is a long-lived radioactive isotope of technetium. Each nucleus decays by emitting one beta particle. What is the product nucleus? www.assignmentpoint.com

  10. The nuclear equation is A Problem To Consider • Technetium-99 is a long-lived radioactive isotope of technetium. Each nucleus decays by emitting one beta particle. What is the product nucleus? • Similarly, from the subscripts, you get www.assignmentpoint.com

  11. The nuclear equation is A Problem To Consider • Technetium-99 is a long-lived radioactive isotope of technetium. Each nucleus decays by emitting one beta particle. What is the product nucleus? • Hence A = 99 and Z = 44, so the product is www.assignmentpoint.com
