1. Understanding the Periodic Table of Elements

4. Left of the “Staircase” are metals:

5. Properties of metals are:

6. Left of the staircase

7. Luster - Shiny

8. Malleable- Can be hammered into a thin sheet

9. Ductile- Can be stretched into wire

10. Good conductors of electricity and heat

11. Higher density

12. High melting point

13. Right side of the staircase are non-metals

14. Properties of non-metals are:

15. Right of the staircase

16. No luster - Dull

17. Brittle

18. Bad conductors of heat and electricity

19. Low density

20. Low melting point

21. Metalloids are along the staircase

22. Properties of both metals and non metals

23. Can be shiny or dull

24. Solid

25. Draw a metal and a nonmetal
Label it with one of the characteristics

26. Pg 93

27. How to read the periodic table

28. Dmitri Mendeleev- Russian chemist who designed the periodic table of elements

29. Periods- Horizontal rows
Elements in a period have similar mass, but different properties

30. Groups or Families- vertical columns
Elements in the same family have similar characteristics and the same number of valence electrons

31. Some families have their own names

32. Alkali Metals
First family
Very reactive because of only 1 valence electron

33. Hydrogen Lithium

34. Alkaline Metals
Second family
2 valence electrons

35. Beryllium Magnesium

36. Halogens
Second to last family
Very reactive

37. Noble gasses
Don’t react with any other elements
Full outer shell

38. Helium Neon
