  1. Today we are going to focus on the Periodic Table! • Activating Strategy… • Brainpop!

  2. A Beautiful Mind This crazy looking man is Russian chemist Dmitri Mendeleev. Mendeleev created the first Periodic Table in 1869.

  3. So why is the PToE important? • ORGANIZATION. • There are a lot of elements on earth. If we don’t know anything about them/what they have in common, we can’t understand them. Think, Pair, Share: (2 minutes) Think back to the end of Earth’s History. We learned about another system of organization that scientists use. What was that system and what did it do?  HINT: Think evolution!

  4. So how is the Periodic Table organized? • Vertical Columns = groups • Horizontal Rows = periods Your periodic table already has the groups (those gray boxes I told you not to color), let’s label the periods.

  5. Each element lives with its own Family • Elements on the periodic table can be grouped into families based on their chemical properties. • Each family has a specific name to differentiate it from the other families in the periodic table. • Elements in each family react differently with other elements.

  6. 1 Week til THXGIVING! 11/15/2012DO NOW! • Findthe element and identify its family: • Group 6, Period 5 • Group 5, Period 4 • Group 17, Period 2 • Noble gas with atomic symbol “Ne” • Transition metal with atomic symbol “Ag” Please do not touch anything on your lab tables!

  7. Let’s mix it up… • 4 stations – 20 minutes at each station. • Each station has notes, directions, an activity, and clean up instructions. • Please be responsible with the materials. • Expectations: • Work together • Low volume • Complete the activity • Stay in your assigned group

  8. Gallery Walkers • Because Ms. K will be working with 1 group of students while you are doing your gallery walk, it is imperative that you follow these rules & directions. • You will have exactly 1 song per station. • Do NOT move until the music changes. • Do NOT move before the music changes. You must be on task, quiet, and at your assigned stations at all times or Ms. K will ask you to sit down.

  9. -Organize on your plate a HELIUM (He) atom! -Draw what your plate looks like 2 H Helium 4.00260

  10. Now change your Helium atom into an ION with a charge of -1 on your plate! • Draw it! 2 H Helium 4.00260

  11. Draw a Beryllium (Be) atom! 4 Be Beryllium 9.01218

  12. Make your Beryllium atom into an Ion with a charge of +2 4 Be Beryllium 9.01218

  13. Draw a Lithium atom. 3 Li Lithium 6.941

  14. Make the Lithium atom into an Ion with a charge of -3. 3 Li Lithium 6.941

  15. ALKALI METALS Group 1 • Hydrogen is not a member, it is a non-metal • 1 electron in the outer shell • Soft and silvery metals • Very reactive, esp. with water • Conduct electricity Image: http://www.learner.org/interactives/periodic/groups2.html

  16. ALKALINE EARTH METALS Group 2 • 2 electrons in the outer shell • White colored and malleable • Reactive, but less than Alkali metals • Conduct electricity

  17. TRANSITION METALS Groups in the middle • Good conductors of heat and electricity. • Some are used for jewelry. • The transition metals are able to put up to 32 electrons in their second to last shell. • Can bond with many elements in a variety of shapes.

  18. Halogens Group 17 • 7 electrons in the outer shell • All are non-metals • Very reactive are often bonded with elements from Group 1

  19. Noble Gases Group 18 • Exist as gases • Non-metals • 8 electrons in the outer shell = Full • Helium (He) has only 2 electrons in the outer shell = Full • Not reactive with other elements

  20. Let’s Practice! • You and your partner are responsible for: • Using your new colored periodic table as a reference. • Answering ALL investigation questions. • Raising your hands when you have questions. • COLLABORATING SUCCESSFULLY to complete work during the given time  • Value- 50 point in class assignment.

  21. Use your knowledge & periodic table to help you identify the following elements. Also include what FAMILY they belong to (complete in your notebook): 1. 3. 4. 2.

  22. Exit Ticket – COMPLETE sentences, separate sheet • HOT Q1: Why is it important to have a system of organization for all of the elements on earth? • HOT Q2: Why do only electrically stable elements live on the Periodic Table? • HOT Q3: What are the 2 most reactive groups? Why are they so reactive?HOT Q4: Why don’t the noble gases react?
