  1. 4. More Particles in the Same Space = More Collisions & Greater Chance of a Reaction
  2. 6. Increasing Contact Points = More Collisions & Greater Chance of a Reaction
  3. 8. Decreasing the space for the same number of particles = More Collisions & Greater Chance of a Reaction
  4. 11. Reactants have More Energy than the Product, Temperature Increases, Thermal Energy is Released
  5. 13. The time that it takes half the nuclei in a sample to decay
  6. 14. Smaller nuclei join together to form larger nuclei and energy is released
  7. 15. Each time a nucleus splits, it releases more neutrons, which can go on and cause more reactions to occur and will continue to happen.
  8. 17. How can Radioactivity be detected
  9. 19. An example of an Endothermic Reaction
  10. 22. Lowers the Activation Energy
  11. 23. Means Out

  1. 1. Any reaction involving a solid takes place where
  2. 2. The splitting of a nucleus into smaller nuclei and the release of energy
  3. 3. Nuclear Reactions Release ______ Energy Than Chemical Reactions
  4. 5. Two smaller nuclei created when a nucleus splits
  5. 7. Reactants have Less Energy than the Products, Temperature Decreases, Thermal Energy is Absorbed
  6. 9. Increasing Energy = Particles move Faster = More Collisions & Greater Chance of a Reaction
  7. 10. Related to Heat
  8. 12. Process Happens in the Sun’s Core
  9. 16. Occurs when a stable isotope is struck by a neutron
  10. 18. An example of an Exothermic Reaction
  11. 20. Means In
