  1. Periodic Table Organization and Properties Periods, Groups and Categories

  2. Highlight and label the zigzag line

  3. What are periods and groups? • The periodic table is further divided into periods and groups. • Each horizontal row is called a period. • Each vertical column is called a group.

  4. Color the group title and label all 18 groups in the same color with arrows Groups are up and down 1 2 3

  5. Color the period title and label all 7 periods in the same color with arrows 1 2 3 Periods are side to side

  6. WHERE ARE THE METALLOIDS LOCATED?

  7. On the zigzag line. Color all of the table tiles (in white below) the same color.

  8. WHERE ARE THE METALS LOCATED?

  9. On the left side (not Hydrogen) Color all of these table tiles the same color

  10. WHERE ARE THE NON-METALS LOCATED?

  11. INERT GASES INCLUDED On the right plus Hydrogen Color all of these the same color

  12. Check for Understanding: • After you pick up the light green sort, find these 3 cards: metals, metalloids, non metals • Place the label cards into three categories according to their position on the periodic table • Sort the rest of the cards into one of the three categories • Raise your hand when you finish

  13. How is the periodic table organized? • The periodic tableorganizes the elements according to how they combine with other elements (chemical properties). • The periodic table is organized in order of increasing atomic number.

  14. Groups…Here’s Where the Periodic Table Gets Useful!! • Elements in the same group have similar chemical and physical properties!! • (Mendeleev did that on purpose.) • Why?? • They have the same number of valence electrons. • They will form the same kinds of ions.

  15. What are physical properties? • Characteristics that you can see through direct observation are called physical properties. • Physical properties include color, texture, density, brittleness, and state (solid, liquid, or gas). • Melting point, boiling point, and specific heat are also physical properties.

  16. What are chemical properties? • Properties that can only be observed when one substance changes into a different substance are called chemical properties. • Any change that transforms one substance into a different substance is called a chemical change.

  17. WHAT DOES THE ZIG ZAG LINE DO?

  18. The Zig Zag line…. • ….separates the metals and the nonmetals. • …. is where you find the metalloids.

  19. Label the periods and groups:notice the atomic number increases with each Periods are side to side Atomic Number increases Groups are up and down

  20. Label the Metals and Non metals Show where the metals and non-metals are located by color coding them on your handout

  21. WHAT ELEMENTS MAKE UP THE MAJORITY OF THE PERIODIC TABLE?

  22. METALS

  23. WHERE ARE THE METALS LOCATED?

  24. On the left side (not Hydrogen)

  25. SCAVENGER HUNT • Fold your paper in half (hot dog style) • Put letters A – M on the left side • Put letters N – Z on the right side • See if you can find an object made of metal for each letter of the alphabet • Objects can be on your body, in your backpack, or in the classroom • GO! A l M Z

  26. WHAT ARE SOME PROPERTIES OF METALS?

  27. Properties of Metals • Shiny and silvery

  28. Properties of Metals • Shiny and silvery • Hard, Malleable, Ductile

  29. HARD

  30. MALLEABLE: they can be shaped or hit with a hammer without breaking into pieces

  31. DUCTILE: they can be bent multiple times without breaking

  32. Properties of Metals • Shiny and silvery • Hard, Malleable, Ductile • High Melting Points (it takes a HIGH temperature to melt)

  33. HIGHEST

  34. 1200 Degrees to melt Silver!

  35. Properties of Metals • Shiny and silvery • Hard, Malleable, Ductile • High Melting Points • Good thermal conductors (heat moves through metal quickly)

  36. Properties of Metals • Shiny and silvery • Hard, Malleable, Ductile • High Melting Points • Good thermal conductors • Good electrical conductors (electricity moves through metal quickly)

  37. WHERE ARE THE NON-METALS LOCATED?

  38. INERT GASES INCLUDED On the right plus Hydrogen

  39. WHAT ARE SOME PROPERTIES OF THE NON-METALS?

  40. Non-metals have properties opposite of the metals

  41. Opposite of the metals • Dull (not shiny) or transparent

  42. Opposite of the metals • Dull(not shiny) or transparent • Fragile (not strong)

  43. Not strong
