Across
  1. 1. Symbols Used in Nuclear Chemistry Reference Table
  2. 5. how to recognize natural transmutation
  3. 6. but in chemistry, OPPOSITES ATTRACT!
  4. 7. conditions needed to force 2 positively charged nuclei together in fusion
  5. 9. BOMBARDING one element with a high energy Table O particle, causing it to turn into another element; (not by itself)
  6. 13. ms; unit of time for half-life
  7. 14. a radioactive atom that emits a beta particle (B-)
  8. 17. t/T; tells you when to stop cutting in half; will always be a whole number (1, 2, 3, 4 or 5)
  9. 19. must equal charge after (numbers on bottom on the left MUST equal numbers on bottom on the right); refer to atomic numbers
  10. 22. elements found in the sun where fusion occurs
  11. 23. mass of 0; +1 charge; (B+); not to be confused with a beta particle
  12. 24. must equal mass after (numbers on top on the left MUST equal numbers on top on the right)
  13. 31. how to recognize artificial transmutation
  14. 32. a radioactive atom that decays by itself; natural transmutation; (See Table N)
  15. 33. mass of 1, +1 charge; (p)
  16. 35. clues that usually indicate a fission reaction
  17. 36. Selected Radioisotopes Reference Table; has info on radioactive elements
  18. 37. E = mc^2; where nuclear energy comes from
  19. 38. one element turns into another element by nuclear decay
  20. 40. = ending mass; not the starting or original mass; double the mass instead of cutting in half
  21. 41. T; usually found in Table N
  22. 42. more energy efficient, cheaper, can be local
  23. 43. cancer, meltdowns, long term storage of wastes, wars
Down
  1. 2. a radioactive atom that emits an alpha particle
  2. 3. aka an electron; mass of 0, - 1 charge (B-); faster = greater penetrating power
  3. 4. a radioactive atom that emits a positron (B+)
  4. 8. amount of time needed to get half as much; constant; unaffected by temperature or pressure
  5. 10. helps detect thyroid disorders
  6. 11. if greater than 1.4, an atom is radioactive (unstable nucleus)
  7. 12. neutrons try to act like these in the nucleus to prevent positive protons from "fighting"
  8. 15. mass of 1; no charge; (n)
  9. 16. mass of 4, charge of +2; (a); heavy & slow = weak penetrating power
  10. 18. no mass, no charge; (Y); fastest = greatest penetrating power
  11. 20. t; the total time that goes by; usually after the word "after"
  12. 21. to connect the masses given in the question
  13. 25. 1/2^t/T; will only ever be: 1/2, 1/4, 1/8, 1/16. 1/32
  14. 26. a radioactive isotope whose pathway can be followed in reactions
  15. 27. 2 nuclei unite to form a heavier nucleus
  16. 28. geological dating of non-living things like Earth
  17. 29. carbon dating of once living things like fossils
  18. 30. used for chemotherapy
  19. 34. if greater than 82, element is radioactive
  20. 39. splitting an atom
