15. CATEGORY 1 - $300 What are neutrons?

16. CATEGORY 1 - $400 All atoms have a nucleus made of protons and neutrons, and electrons outside the nucleus in an electron cloud. This describes what?

17. CATEGORY 1 - $400 What do atoms of different elements alike? - Basic atomic structure

18. CATEGORY 1 - $500 This is the sum of protons and neutrons

19. CATEGORY 1 - $500 What is the atomic mass?

20. CATEGORY 2 - $100 This is what atoms do in order to fill their valence electron level.

21. CATEGORY 2 - $100 Why do atoms bond with other atoms?

22. CATEGORY 2 - $200 This bond has oppositely charged particles attracted to each other

23. CATEGORY 2 - $200 What is an ionic bond?

24. CATEGORY 2 - $300 In this bond, electrons are not shared evenly around the molecule

25. CATEGORY 2 - $300 What is a polar (covalent) bond)

27. CATEGORY 2 - $400 In this process, chemical bonds break and new bonds form as atoms are rearranged to form new substances

28. CATEGORY 2 - $400 What happens in a chemical reaction?

29. CATEGORY 2 - $500 This bond forms when both atoms need more electrons to fill their valence levels.

30. CATEGORY 2 - $500 When do covalent bonds form?

31. CATEGORY 3 - $100 This describes the water molecule because the oxygen end of water has a partial negative charge and the hydrogen end has a partial positive charge.

32. CATEGORY 3 - $100 Why is water a polar molecule?

33. CATEGORY 3 - $200 This is the property caused when hydrogen bonds pull water molecules together

34. CATEGORY 3 - $200 What is cohesion?

35. CATEGORY 3 - $300 High surface tension and high heat capacity are caused by this behavior of water

36. CATEGORY 3 - $300 What is cohesion?

37. CATEGORY 3 - $400 Water will dissolve most substances needed by cells because of this property.

38. CATEGORY 3 - $400 What is adhesion?

39. CATEGORY 3 - $500 Water uses both cohesion and adhesion for this property important to plants and animals.

40. CATEGORY 3 - $500 What is capillary action?

41. CATEGORY 4 - $100 This is the main component in a liquid mixture.

42. CATEGORY 4 - $100 What is solvent?

43. CATEGORY 4 - $200 This is what pH measures in a solution.

44. CATEGORY 4 - $200 What is hydrogen ion concentration?

45. CATEGORY 4 - $300 In a neutralization reaction, an acid plus a base will yield water plus this substance.

46. CATEGORY 4 - $300 What is a salt?

48. CATEGORY 4 - $400 In this type of substance, chemical bonds do not break when it dissolves in water.

49. CATEGORY 4 - $400 What is a molecule? (covalently bonded)

55. CATEGORY 5 - $200 What is radioactive carbon? (carbon 14)

56. CATEGORY 5 - $300 Water on the surface of our skin will cool the body because it does this.

57. CATEGORY 5 - $300 What is evaporate?

58. CATEGORY 5 - $400 Elements bonded ionically always form this shape.

59. CATEGORY 5 - $400 What is a crystal (lattice)?
