1. Q2:
What property did Mendeleev use to arrange his periodic table?
How many periods are in the periodic table and what information can you tell by an element’s period?
Where are the groups and what information do they give you about an element?
What can you know about all the elements in group 2A?
What information is contained inside the element square?

2. Your 2 cents wanted….

3. A groups
For the 8 “a’” groups, the group # is the # of valence (outershell) electrons

4. Modern periodic table Four pieces of info for each element
Name of element
Symbol
Atomic number
Atomic mass

5. Outline all of the Metals in Black

6. Transition metals are located in groups 3-12 (AKA B groups)

7. Transition metals
Form a bridge between the elements on the left and those on the right
Form compounds with distinctive colors

8. Color the Transition metals dark green
DON’T COLOR THE ELEMENTS
THAT ARE BLACKED OUT!
WE ONLY WANT
TO COLOR
METALS!!!
Become more Metallic

9. Color the inner transition (lanthanide & actinide) metals light green
DON’T COLOR THE ELEMENTS
THAT ARE BLACKED OUT!
THEY ARE NOT METALS!
WE ONLY WANT
TO COLOR
METALS!!!
Become more Metallic

10. Metalloids
Elements with properties that fall between those of metals and nonmetals
All touch stairs
Except Al, it is a metal
Metalloids ability to conduct electric current varies with temp
Pure silicon and germanium good insulators at low temp good conductors at high temp

11. Outline all of the Metalloids in Green

12. Nonmetals Poor conductors of heat and electricity
Low boiling points, so most are gases at room temp
Solids at room temp are brittle
Fluorine is most reactive nonmetal
To the right of stairs
As you go from bottom to top the nonmetallic properties increase

13. Outline the nonmetals!! In red
Become more NonMetallic

14. Think fast!!! What does the period # tell you? # of energy levels
What does the A group # tell you?
# of valence electrons
How many periods on periodic table? 7
Other names for groups?
Columns, families

15. Periodic table
Why is hydrogen located on the left side with group 1- active metals……shouldn’t it be with the other gases in group 17?
Hydrogen’s location is based on it’s electron configuration (Valence Electrons)…..not it’s properties

16. Valence Electrons (aka the outer shell electrons!!)
Is an electron in the highest occupied energy level of an atom
Key role in chemical reactions
Elements in a group have similar properties because they have the same number of valence electrons
For the “a” groups, the group number tells how many valence electrons there are

17. Alkali metals Group 1A One valence/outer shell electron
Extremely reactive
Reactivity increases as you go down the column
Francium is the most reactive
Label on reference table

18. Color the Alkali Metals Red

19. Alkaline Earth metals Group 2a Two valence e-
HARDER THAN METALS IN GROUP 1A
REACTIVIY IS SHOWN BY THE WAY EACH ELEMENT REACTS W/ WATER
Label on reference table

20. Color the Alkaline Earth Metals Blue\\

21. The Boron Family Group 3a 3 valence e-
ALUMINUM IS THE MOST ABUNDANT METAL IN EARTH’S CRUST!!!

22. Color the Boron Family Brown

23. The Carbon Family Group 4a 4 valence e-
MOST OF Compounds IN YOUR BODY CONTAIN CARBON!!
Silicon is the 2nd most abundant element in Earth’s crust!
Label on reference table

24. Color the Carbon Group Purple

25. The Nitrogen Family Group 5a 5 valence e-
Nitrogen & Phosphorus are used in fertilizers
Bodies-control reaction & release energy from food

26. Color the Nitrogen Group Pink

27. The Oxygen Family Group 6A 6 valence e-
Oxygen is most abundant element in the Earth’s crust

28. Color the Oxygen Group Light Blue

29. The halogen group Group 7A 7 valence e-
Label on reference table
Group 7A
7 valence e-
Highly reactive (fluorine is the most reactive nonmetal)
Reactivity increases from bottom to top

30. Color the Halogens Orange

31. The noble gases Group 8A 8 valence e- (EXCEPT He –IT ONLY HAS 2)
Colorless, odorless, & EXTREMELY UNREACTIVE!!
“stable elements

32. Color the Noble Gases Yellow

33. Think Fast!!! Most reactive nonmetal? Most Reactive metal?
Fluorine
Most Reactive metal?
Francium
What is special about Helium
Only 2 valence e-
DESCRIBE THE NOBLE GASES?
STABLE, UNREACTIVE, ODORLESS, COLORLESS

34. How does Heat Move?

35. Exploring Heat
Question: In what direction does heat move?
Research: What are 3 ways heat moves?
Hypothesis: I think fluids move heat by ________.

36. Procedure:
1. Heat water in tea pot.
Fill the large beaker ¾ full with water directly from the tap.
3. Put 3 drops of food coloring in the small beaker.

37. 4. Cut a piece of plastic wrap large enough to
4. Cut a piece of plastic wrap large enough to securely cover the small beaker.
5. Fill the small beaker with hot water to the top. Mix the food coloring in.
Cover the small beaker tightly with the plastic wrap and
secure it with a rubber
band.

38. 7. Use the tongs to carefully lower the small
7. Use the tongs to carefully lower the small beaker full of hot water into the large beaker.
8. Use a knife to make a slit in the plastic wrap.

39. 9. Observe the beakers. Record your observations. Sketch what you see.

40. 10. Conclusion: The answer to your question.
Explain what in your observations is evidence to support your conclusion.
Question: How does heat move in fluids (air and liquids)?
11. Clean up your area. Return clean dry items to the tub. Place waste in the trash cans. Put goggles neatly in the sterilizer.
