  1. Today in I.S.… Week #1 Quarter 2 (10/16-10/17) • Pick Up: • Warm up sheet • Periodic table?? • Find that element! • Bill Nye Video ?’s • I.S. Learning Goal: • I can describe the features and components of the atom. • I can apply models to features of an atom Warm Up Question:What are the parts that make up an atom and where are they located? Fact of the Day The noble gas Xenon lasers can cut through materials that are so tough even diamond tipped blades will not cut. • To Do Today: • New seating chart • Complete coloring of periodic table • Bill Nye video with handout on Atoms • Find that Element! handout • Periodic Table of Elements Review handout Homework: New Notebook Friday 10/18

  2. Families on the Periodic Table • Elements on the periodic table can be grouped into families bases 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.

  3. ALKALI METALS • Group 1 • Hydrogen is not a member, it is a non-metal • All are metals and solid at room temp • 1 Valence Electron • Soft and silvery, shiny • Very reactive, esp. with water • Conduct electricity Image: http://www.learner.org/interactives/periodic/groups2.html

  4. ALKALINE EARTH METALS • Group 2 • Metals • Be,Mg,Ca,Sr,Ba,Ra • Solids at room temp • 2 electrons in the outer shell • White, silvery, and malleable • Reactive, but less than Alkali metals • Conduct electricity

  5. TRANSITION METALS • Metals • Almost all are solids at room temp (Hg) • Good conductors of heat and electricity. • 1 or 2 Valence Electrons • Less Reactive than Alkali and Alkaline Earth • Can bond with many elements in a variety of shapes.

  6. BORON FAMILY • Group 3 • 3 (valence)electrons in the outer shell • Most are metals • Boron is a metalloid all other elements are metal. • Reactive • Solid at room temp

  7. CARBON FAMILY • Group 4 • 4 (valence) electrons in the outer shell • Contains 3 metals (Fl, Pb, Sn), 2 metalloids(Si, Ge), and 1 non-metal Carbon (C) • Reactivity varies • Solids at room temp

  8. NITROGEN FAMILY • Group 5 • 5 electrons in the outer shell • Can share electrons to form compounds • Contains 2 metals(Bi,Sb) , 2 metalloids(As,’Pb), and 2 non-metals(P,N) • Reactivity Varies • Nitrogen is the only gas at room temp, rest are solids

  9. OXYGEN FAMILY • Group 6 • 6 electrons in the outer shell • Contains 2 metals(Po,Lv), 1 metalloid(Te), and 3 non-metals(O, S, Se) • Reactive • Oxygen is a gas, the rest are solids at room temp

  10. Halogens • Group 7 • 7 electrons in the outer shell • Non-metals, Uus is unknown • Very reactive - are often bonded with Group 1 Alkali Metals • Has 2 gases(F, Cl), 1 liquid (Br), and 2 solids

  11. Noble Gases • Group 8 • 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

  12. Rare Earth Metals • Some are Radioactive • The rare earths are silver, silvery-white, or gray metals. • Conduct electricity

  13. Bill Nye: • Atoms - Video • with Questions

  14. You may watch more videos about the elements at: • http://www.periodicvideos.com/

  15. Today in I.S.… Week #1 Quarter 2 (10/18) • I.S. Learning Goal: • I can describe the features and components of the atom. • I can apply models to features of an atom Fact of the Day Carbon is most commonly obtained in coal deposits. Diamonds are found in volcanic rock, called kimberlite, located in South Africa, Arkansas, and elsewhere. Name is Latin for charcoal. Warm Up Question: Why is carbon important in the study of organic chemistry? • To Do Today: • Check for notebook • Discuss Lewis Dot structure and Bohr Model of atomic diagrams Homework: notebook cover Monday Notebook set up Monday Cheat song: http://www.bing.com/videos/search?q=cheet+song&qs=n&form=QBVR&pq=cheet+song&sc=8-10&sp=-1&sk=#view=detail&mid=0F0601B0607AC390F2280F0601B0607AC390F228

  16. Periods • Each row is called a “period” • The elements in each period have the same number of shells 1st Period = 1 Shell 2nd Period = 2 Shells 3rd Period = 3 Shells 4th Period = 4 Shells Periodic table of elements video http://www.brainpop.com/science/matterandchemistry/periodictableofelements/

  17. Groups Group 8 = 8 electrons Except for He, it has 2 electrons Group 1 = 1 electron Group 2 = 2 electrons • Each column is called a “group” 3 4 5 67 • Each element in a group has the same number of electrons in their outer orbital, also known as “shells”. • The electrons in the outer shell are called “valence electrons” www.chem4kids.com

  18. Transition Metals • Transition Metals have slightly different rules for shells and valence electrons. www.chem4kids.com

  19. Lewis Structures Put onto back of “Find that Element!” handout • Find your element on the periodic table. • Determine the number of valence electrons. • This is how many electrons you will draw. 20

  20. Lewis Structures • Find out which group (column) your element is in. • This will tell you the number of valence electrons your element has. • You will only draw the valence electrons. 21 www.chem4kids.com

  21. Groups - Review Except for He, it has 2 electrons • Each column is called a “group” • Each element in a group has the same number of electrons in their outer orbital, also known as “shells”. • The electrons in the outer shell are called “valence electrons” 22 www.chem4kids.com

  22. Order of How to Draw Lewis Dot Structures

  23. Lewis Structures • Write the element symbol. • Carbon is in the 4th group, so it has 4 valence electrons. • Starting at the right, draw 4 electrons, or dots, counter-clockwise around the element symbol. 24

  24. Lewis Structures • Check your work. • Using your periodic table, check that Carbon is in the 4th group. • You should have 4 total electrons, or dots, drawn in for Carbon. 25

  25. Lewis Structures • On back your worksheet “Its Elemental”, try these elements on your own: • H • P • Ca • Ar • Cl • Al 26

  26. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 27

  27. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 28

  28. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 29

  29. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 30

  30. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 31

  31. Lewis Structures • On your worksheet, try these elements on your own: • H • P • Ca • Ar • Cl • Al 32
