13. CheerSilenceLoseTimerBooTheme Three types of nuclear radiation

14. CheerSilenceLoseTimerBooTheme alpha, beta, gamma

15. CheerSilenceLoseTimerBooTheme What are the benefits of fission?

16. CheerSilenceLoseTimerBooTheme huge amounts of energy; plenty of resource

17. CheerSilenceLoseTimerBooTheme What are the reactants and products in a fission reaction?

18. CheerSilenceLoseTimerBooTheme A neutron bullet and a fissionable isotope are reactants; more neutrons and smaller fragments are the products

19. CheerSilenceLoseTimerBooTheme What % of the U.S. energy is gotten from nuclear power?

20. CheerSilenceLoseTimerBooTheme Around 20%

21. CheerSilenceLoseTimerBooTheme part of the atom involved in a normal chemical reaction

22. CheerSilenceLoseTimerBooTheme What is an electron

23. CheerSilenceLoseTimerBooTheme Part of the atom involved in a nuclear reaction.

24. CheerSilenceLoseTimerBooTheme nucleus

25. CheerSilenceLoseTimerBooTheme Who discovered radiation

26. CheerSilenceLoseTimerBooTheme Becquerel

27. CheerSilenceLoseTimerBooTheme What isotope of uranium was found to be easily fissionable?

28. CheerSilenceLoseTimerBooTheme U-235

29. CheerSilenceLoseTimerBooTheme Compare and contrast fission and fusion.

30. CheerSilenceLoseTimerBooTheme both release high amounts of energy; both are nuclear reactions (involve the nucleus); fission is "splitting" a nucleus, fusion is combining 2 smaller nuclei; fission happens in nuclear power plants and atomic bombs, fusion is only observed on the sun.

31. CheerSilenceLoseTimerBooTheme What is fission?

32. CheerSilenceLoseTimerBooTheme a nuclear reaction that invlolves the splitting of a heavy nucleus into a lighter nucleus.

33. CheerSilenceLoseTimerBooTheme What is alpha, beta, and gamma

34. CheerSilenceLoseTimerBooTheme The elements used in the atomic bomb

35. CheerSilenceLoseTimerBooTheme What is the property of an alpha particle

36. CheerSilenceLoseTimerBooTheme Least penetrating form of radiation

37. CheerSilenceLoseTimerBooTheme What type of reaction does fission lead to?

38. CheerSilenceLoseTimerBooTheme Chain Reaction

39. CheerSilenceLoseTimerBooTheme When can mass be converted to energy?

40. CheerSilenceLoseTimerBooTheme Only during a nuclear reaction

41. CheerSilenceLoseTimerBooTheme What is half-life

42. CheerSilenceLoseTimerBooTheme Average time it takes for half the amount of a radioactive element to decay

43. CheerSilenceLoseTimerBooTheme Thorium-234 has a half-life of 24 days, started with 100 g how much is left after 48 days?

44. CheerSilenceLoseTimerBooTheme 25 grams

45. CheerSilenceLoseTimerBooTheme Plutonium-239 is 24,110 years how much of 100 g remains after 96,400 years?

46. CheerSilenceLoseTimerBooTheme 6.25 grams

47. CheerSilenceLoseTimerBooTheme Radium-266 has a half life of 1599 years, how much of 15.0 mg is left after 6369 years.

48. CheerSilenceLoseTimerBooTheme 0.94 mg

49. CheerSilenceLoseTimerBooTheme Thorium-227 is 16 days, how many days are required for three- fourths to decay?

50. CheerSilenceLoseTimerBooTheme 32 days

51. CheerSilenceLoseTimerBooTheme What is fusion?

52. CheerSilenceLoseTimerBooTheme Two smaller nuclei combining to form a larger nucleus, releasing tremendous amounts of energy. Type of reaction that occurs in the stars.

53. CheerSilenceLoseTimerBooTheme Why isn't fusion used in power plants?

54. CheerSilenceLoseTimerBooTheme required temperatures are too high

55. CheerSilenceLoseTimerBooTheme Name of uranium bomb used in WWII

56. CheerSilenceLoseTimerBooTheme Little Boy

57. CheerSilenceLoseTimerBooTheme What are the downsides of using fission as an energy source?

58. CheerSilenceLoseTimerBooTheme nuclear waste; danger of out-of-control chain reaction

60. CheerSilenceLoseTimerBooTheme What are some productive uses of nuclear chemistry in medicine?

61. CheerSilenceLoseTimerBooTheme MRI and CT

62. CheerSilenceLoseTimerBooTheme What is an alpha particle?

65. CheerSilenceLoseTimerBooTheme This particle has average penetrating power and ionizing ability.

66. CheerSilenceLoseTimerBooTheme What is electron capture?

67. CheerSilenceLoseTimerBooTheme This process combines electrons and protons to form neutrons.

68. CheerSilenceLoseTimerBooTheme Who is Ernest Rutherford?

69. CheerSilenceLoseTimerBooTheme He is the discoverer of alpha and beta rays.
