3. Name properties of metals.

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

5. Name properties of
non-metals.

6. -Dull

bendable
Brittle- hard; breaks apart
Ductile-can be drawn into
wire.

13. What are metalloids and give examples of them.

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

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

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

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

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

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

20. Physical

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

22. Chemical

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

24. Physical

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

26. Chemical

27. A candle burns and
becomes smaller
over time.

28. Chemical

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

30. Physical

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

32. Chemical

33. Healing of a cut
on your hand.

34. Chemical

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

36. Chemical

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

38. Physical

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

40. Physical

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