5. The History of the Periodic Table
Dmitri Mendeleev (1869)
Rearranged some elements so that they would line up with other elements with similar chemical properties.
Example: Tellurium & Iodine
***Probably won’t get to this on day 1.

6. The Periodic Table
All of the elements in the same horizontal row on the periodic table make up a period.

7. The Periodic Table
All of the elements found in the same vertical column make up a group or a family.
Elements in a group have tend to have similar chemical properties

8. Textbook Hunt Elements in the same group have similar properties.
There are four main groups we are going to be researching today: Alkali Metals, Alkaline Earth Metals, Halogens and Noble Gases.

9. Textbook Hunt
Work with your elbow partner to complete the Textbook Hunt worksheet.
Any of the information on this worksheet could be on your next quiz/test.
We will go over this together in class!

11. Exit Slip
Turn in your worksheet, then work on homework questions.

Notes on Metals and Nonmetals

17. Video
Take note of:
Characteristics of each group that makes it unique!

18. Examples of METALS
Most metals are solids at room temperature (except for Mercury)
Most metals are HARD (except Lithium, Potassium, Sodium)
Other Examples: Copper,
Aluminum, and Zinc

19. Physical Properties of METALS
Metals have shiny luster. (or metallic luster)
LUSTER – the way an object’s surface reflects light

20. Best conductors: silver and copper
When you leave a spoon in a cup of hot drink, the bit poking out of the drink gets hot. Why?
Conduction!!
METALS are the best conductors of heat.
Electrons in metals move more freely than in non-metals, allowing the heat energy to travel across the metal.
For example, when the spoon touches the hot drink, the heat from the drink excites the electrons in the metal, and the electrons transfer the energy from one electron to another, carrying the heat all the way up the spoon quickly.
Best conductors: silver and copper

21. Physical Properties of METALS
Metals are good conductors of electricity.
Copper, silver, and gold are good electrical conductors. In a conductor, electric current can flow freely.
Since metals have free electrons, they can carry a charge easily.
Copper Wiring

22. Physical Properties of METALS
Metals are malleable.
Malleable or Malleability - metals ability to be shaped or formed
Ex: Aluminum is malleable.

23. Physical Properties of METALS
Metals are ductile.
Ductility or ductile – can be drawn into a wire

24. Chemical Properties of METALS
Metals react with acids and can undergo oxidation (rust)
Non-metals do not.

25. Chemical Properties of Metals
Most metals have 3 or less valence electrons
Most likely to LOSE electrons = Form cations  25

26. Non metals may be solids, liquids or gases.
Examples of NONMETALS
Non metals may be solids, liquids or gases.
Examples:
Solids – Carbon, Sulfur, Phosphorus
Liquid – Bromine
Gases – Oxygen, Hydrogen, Nitrogen

27. Physical Properties of NONMETALS
Nonmetals have a dull luster.
(They are not shiny!)
Example: Phosphorus

28. Physical Properties of NONMETALS
Nonmetals are insulators.
They do not conduct electricity or heat well.
The atoms in nonmetals do not have loose electrons. Therefore, when electricity, or something hot touches a non-metal, the energy does not move quickly through the material.
What would you rather stir a hot pot with—a wooden spoon or a metal spoon?

29. Physical Properties of NONMETALS
Nonmetals are soft (except for diamonds) and brittle.
Example: Sulfur

30. Chemical Properties of Nonmetals
Nonmetals have 5 or more valence electrons and usually gain electrons in chemical bonds = form anions. 30

31. An interesting nonmetal: Carbon
Ever break the point of your pencil? That’s because it’s made of graphite, a substance made up completely of Carbon—a brittle nonmetal.
Carbon atoms in graphite
However diamonds, the hardest material of all, are made of the same element: Carbon. Look at how the carbon atoms are arranged in diamonds—why do you think diamonds are harder than graphite?
You may also want to discuss how we are using carbon to create new materials such as nanotubes, or discuss buckeyballs.

32. The elements contained in the classification of Metalloids:

33. METALLOIDS
Elements classified as Metalloids have physical properties of both metals and non-metals.
Some are shiny, some are dull, they are somewhat malleable and ductile, and can conduct heat and electricity at a lesser level than metals.
SILICON
ARSENIC
BORON

34. METALLOIDS
Some metalloids are useful semiconductors, which are used in electronics (radio, computers, telephones, etc.)
They are useful because they conduct just the right amount of electricity or heat.

35. Location: Metals: Left (Green) Nonmetals: Right (Yellow) Metalloids: Along the staircase! (Blue)

41. Annotate
Look over Model 1 quietly. Annotate any questions you have, patterns you notice, and note any information that jumps out at you and seems important.
Be prepared to share your annotations with the class!

42. Electron Configuration Inquiry
Work in the same groups as last time. Ms. Kline has handed you a role card. Write your role at the top of your page.
The spokesperson may ask up to 3 questions before points are deducted from your group.

43. Exit Ticket Reflect: How well did your group work together?
How well did each member of the group contribute?
What changes need to be made for your group to finish all of your work tomorrow?
