20. Density

21. A measure of the ratio between the mass of a substance and the volume it occupies Ex. The density of water is 1 g/ml

22. Magic Triangle

23. M D V Density= Mass / Volume Volume= Mass / Density Mass= Density x Volume

26. Viscosity

27. The ability of a liquid to flow freely Ex. Water has high viscosity while syrup and molasses has low viscosity

28. Physical Change

29. A change in a substance that does not involve forming a new substance

30. Chemical Property

31. A description of what a substance does when it reacts to produce a new substance Ex. Flammability, Combustibility, Reactivity

32. Combustibility

33. The ability of a substance to burn quickly and easily Ex. Magnesium is combustible

34. Flammability

35. The ability of a substance to catch fire Ex. Ether alcohol is highly flammable

36. Reactivity

37. The likelihood that a substance will respond/change when exposed to another substance/element Ex. The Alkali Metals are highly reactive

38. 5 Signs of a Chemical Change

39. 1. Bubbles are produced 2. Colour change indicating new substance 3. Change of odour 4. Light and/or heat is produced 5. Precipitate is formed

40. Atom

41. The smallest unit of measurement for all matter

42. Subatomic Particles

43. -The 3 different parts of an atom -They make up the mass of an atom -Proton, Neutron, Electron

44. Proton

45. -Subatomic particle found in the nucleus -Positive charge -Cannot move

46. Electron

47. -Subatomic particle found on orbit -Negative charge -Moves from atom to atom, causing reactions

48. Neutron

49. -Subatomic particle found in the nucleus - No charge (neutral) -Cannot move

50. Element

51. -A pure substance in its simplest form -Found on the periodic table -Can be identified by unique properties Ex. Boron (B), Carbon (C), Neon (Ne)

52. Molecule

53. A substance made up of 2 or more atoms - Can be molecular element (Ex. O 2 ) -Can be molecular compound (Ex. C 3 H 8

54. Compound

55. A substance made up of 2 or more elements Ex. H2O or water is made of Hydrogen AND Oxygen

56. Atomic Number

57. A number assigned to an element, indicating its position in the periodic table and the number of protons/electrons of element

58. Period

59. Rows in the periodic table

60. Group / Chemical Family

61. -Columns in periodic table -Each element in a chemical family has similar chemical properties Red= Alkali Metals Orange= Alkaline Earth Metals Royal= Halogens Purple= Noble Gasses

62. Metals

63. -Shiny, malleable, conductive substances - Often solids at room temperature -Make up the majority of the periodic table

64. Non-Metals

65. -Dull, brittle substances that are poor conductors of electricity - Often gas at room temperature - Found to the right of the periodic staircase

66. Metalloids

67. -Share some characteristics of metals and some of non- metals - Semiconductors -Found on the periodic staircase
