  2. Name properties of metals.

  3. -shiny-reacts with HCl and CuCl2-conductive-malleable

  4. Name properties of non-metals.

  5. -Dull -Brittle -Non-reactive with HCl and CuCl2

  6. Define: Malleable- Brittle- Ductile-

  7. Malleable- Flexible or bendable Brittle- hard; breaks apart Ductile-can be drawn into wire.

  8. Name five metals.

  9. -Gold, silver, iron, zinc, copper, etc.

  10. Name five non-metals.

  11. - carbon, nitrogen, helium, chlorine, neon, etc.

  12. What are metalloids and give examples of them.

  13. -Substances that share properties of metals and non-metals. -B, Al, Si, Ge, etc.

  14. What is a physical change and give two examples.

  15. -where the original substance remains -melting, density, conductivity.

  16. What is a chemical change and give two examples.

  17. -where a new substance is created. -metal “rusting”, fuel burned.

  18. Metals when pure have a high luster (are shiny).

  19. Physical

  20. Plants carry on photosynthesis in order to make food and oxygen.

  21. Chemical

  22. Metals are typically much better conductors of heat and electricity than are non mentals.

  23. Physical

  24. Bread dough increases in volume if it is allowed to “rise” before baking.

  25. Chemical

  26. A candle burns and becomes smaller over time.

  27. Chemical

  28. Metals are typically ductile (can be drawn into wire).

  29. Physical

  30. Nitrogen gas, which is relatively non reactive, can form nitrogen oxides at the high temperatures of an operating automobile engine.

  31. Chemical

  32. Healing of a cut on your hand.

  33. Chemical

  34. Argon gas, rather than air, is used in many light bulbs to prevent oxidation (“rusting”) of the metal filaments.

  35. Chemical

  36. Tungsten’s high melting point makes it useful for light bulb filaments.

  37. Physical

  38. The hardness of diamonds enables them to be used on drill bits.

  39. Physical

  40. Mercury’s high density and liquid state at room temperature make in useful in barometers.

  41. Physical

  42. Copper has a reddish brown color.

  43. Physical

  44. A puddle of rain water evaporates after a couple of days.

  45. Physical

  46. Sodium chloride, table salt, is dissolved in water.

  47. Physical

  48. Some metals become dull when exposed to air.

  49. Chemical
