  1. CHAPTER24 Nuclear Energy II. Nuclear Reactions (p.689-691)

  2. A. Types of Radiation • Alpha () • helium nucleus paper 2+ • Beta-minus (-) • electron lead 1- • Gamma () • high-energy photon concrete 0

  3. B. Nuclear Decay TRANSMUTATION • Alpha Emission • Beta Emission

  4. C. Fission • splitting a nucleus into two or more smaller nuclei • some mass is converted to large amounts of energy

  5. C. Fission • chain reaction - self-feeding reaction

  6. D. Fusion • combining of two nuclei to form one nucleus of larger mass • produces even more energy than fission • occurs naturally in stars

  7. E. Law of Conservation Of Mass • ALL NUCLEAR EQUATIONS MUST FOLLOW THE LAW OF CONSERVATION OF MASS. • The masses on the reactants must equal the masses on the products.
