11. This Scientist discovered the Neutron in 1932.

12. Who is James Chadwick? (Jimmy Neutron)

13. This Scientist came up with the idea that electrons orbit around the nucleus in energy levels by giving energy to atoms to excite electrons to the next level.

14. Who is Neils Bohr? (Bohr...ring )

15. This Scientist Discovered the electron and its negative charge. He thought that electrons were evenly spaced throughout a positive sphere.

16. Who is J. J. Thompson? (Chocolate Chip Cookie Model)

17. This Scientist brought back the Atomic Theory with evidence. He had four key postulates that he wanted everyone to know.

18. Who is John Dalton?

19. This Scientist performed the Gold Foil Experiment and found that the majority of an Atom’s mass in the center which he called the nucleus. He also found positively Charged particles called protons in the nucleus.

20. Who is Ernest Rutherford?

21. The elements in the periodic table were originally organized by their Atomic Mass, but now they are organized based on this.

22. What is the Atomic #? (# of Protons)

23. Elements in the Same Period on the Periodic Table have the same number of these.

24. What is Energy Levels? (Rings)

25. This is the Number of Valence Electrons that every element in the Boron Family has.

26. What is 3 Valence Electrons?

27. He published the 1 st effective version of the Periodic Table.

28. Who is Dmitri Mendeleev?

29. This is the element in the Nitrogen Group with the largest Atomic Radius.

30. What is Bismuth?

31. This is found in energy levels around the nucleus and has a negative charge.

32. What is an Electron?

33. This was discovered by James Chadwick to have a neutral charge?

34. What is a Neutron?

35. This is found by subtracting the Atomic Number from the Atomic Mass.

36. What is the Number of Neutrons?

37. The number of these defines what the element is.

38. What is the Number of Protons? (Atomic #)

39. This is what you get when you add up the total number of Protons and Neutrons together.

40. What is the Average Atomic Mass?

41. These go in the center of every Bohr Model.

42. What are the # of Protons and the # of Neutrons?

43. This is the # of electrons that they 3 rd Energy Level can hold.

44. What is 8 electrons?

45. Daily Double!

46. This is the order in which you fill the Energy Levels of a Bohr model with electrons.

47. What is filling inside Energy levels first, then outside Energy Levels next?

48. This is how many Valence Electrons the Element has in the 4 th period of the Alkaline Earth Metal Group.

49. What is 2 Valence Electrons?

50. This is how many Energy Levels is needed to house 17 electrons in a Bohr Model.

51. What is 3 Energy Levels?

52. The Smallest unit of an element that maintains the properties of that element.

53. What is an “Atom”?

54. A substance that cannot be separated or broken down into simpler substances by chemical means. All atoms in this substance have the same atomic #.

55. What is an Element? (Same Atomic # = Same Number of Protons)

56. This is the # of electrons in the outer most shell of an atom. This tells you how the atom will react.

57. What is a Valence Electon?

58. A Substance made up of atoms of two or more different elements joined together by Chemical Bonds.

59. What is a Compound?

60. The sand on a beach is an example of this because it has two or more substances that are not chemically combined.
