1. Marking-Up Your Periodic Table
First label the regions of your PT:
Metals
Nonmetals
Metalloids

2. Marking-Up Your Periodic Table
Label the gases (g)
Label the liquids (l)

4. Marking-Up Your Periodic Table
Number the groups to indicate the number of valence electrons.

5. Marking-Up Your Periodic Table
Number the periods. Draw arrows to show the two series’ at the bottom are inserted above (look at atomic #) Period #=Electron Shells

6. Marking-Up Your Periodic Table
Label the groups:
Noble Gases
Halogens
Alkali metals
Alkaline Earth metals
Transition Metals

7. Marking-Up Your Periodic Table
Label the reactivity of metals.

8. Marking-Up Your Periodic Table
Label the reactivity of nonmetals.

9. Recall: Electrons in outer shell
Recall: Electrons in outer shell! Compounds like to group in a way that makes 8 electrons in the outer shell!

10. Families that Get Along!
Based on valence electrons, halogens most like to combine with which family?
WHY don’t the noble gases combine with other elements?
Helium is a noble gas, and is happy, but does NOT have 8 electrons in it’s outer shell. Why is it happy?
