Yes, we have a NEW seating chart. • Once you have found your seat, please pick up a “Prescription for Success” sheet on the front table • As you pick that up, I will be handing you your Progress Report. • Please complete the Prescription for Success, quietly and individually. • When you are finished, please staple the two sheets together and place in the black box.

3. Housekeeping 4th period- Lunch duty is on the white board  • USA Test Prep • Great job to those who completed the first one! It really helped out grades  • USA Test Prep Test recovery #2 is due Friday, October 6. • I am missing some “Poster Projects.” Please get those to me by Wednesday. • Missing/ No Name assignments are put on the side of the cabinet • Graded work/ “lost” notebooks are put in your colored bins • Make sure you check your “make up” folders by my desk whenever you are out.

4. Just gotta… • ASAP Science Presents…The Periodic Table Song • https://www.youtube.com/watch?v=zUDDiWtFtEM • One more • https://www.youtube.com/watch?v=zGM-wSKFBpo • I lied! Last one – just cuz I LOVE me some HP! • https://www.youtube.com/watch?v=v1TfPDlA1xE

5. EQ: What 2 particles are found in the nucleus of an atom? (TOP LEFT) • Title your page: ATOMIC STRUCTURE • Please start this on pg. 38 in IAN • The right page after Bill Nye Notes

6. Atomic Structure • Element – matter that is composed of one type of ATOM • Elements are abbreviated in scientific shorthand – either a letter or a pair of letters called a chemical symbol. • Example: Aluminum = Al Copper = Cu

7. Atomic Structure • Atom – smallest piece of matter that still has the properties of the element; made of 3 types of particles: • Protons – positive (+) • Neutrons – neutral • Electrons – negative (-) DRAW THIS

8. Atomic Structure • Nucleus – located in the center of an atom and consists of protons and neutrons; electrons surround the nucleus • Electron Cloud (shells) – (current) model which shows electrons traveling in specific energy levels (shells) around a nucleus • Electrons closest to nucleus have LOW energy • Electrons farther away have HIGH energy

9. Atomic Structure • Copy the Table **Last energy level (shell) can ONLY hold a MAX of 8 electrons – H and He are exceptions**

10. Answer the EQ: What 2 particles are found in the nucleus of an atom? (TOP RIGHT) • Please draw the Bohr model for Lithium and Neon. Draw this on page 39. • Once you’re finished come pick up a yellow sheet for your 5 question “quiz.” • Please tape in your 5 question exit ticket onto page 39 in IAN.

11. Bellringer 10/3 • Please draw the Bohr model for Nitrogen • Atomic # is 7 • Atomic mass is 14

12. 7th period • Please pick up a yellow 5 question “mini quiz” from the front • Complete it quietly and tape it into pg. 39 • When you are finished, please pull out your periodic table.

13. Let’s check our 5 question “quiz” • What particle is NOT located in the nucleus? B. Electron • The smallest piece of matter that still has the properties of an element is a(n)? C. Atom • Protons have a _____ charge. A. Positive • Neutrons have a _____ charge. C. Neutral • Electrons have a _____ charge. B. Negative

14. EQ: What is the difference between atomic number & atomic mass? (TOP) • Title your page: MASSES OF ATOMS • On page 40 in IAN

15. MASSES OF ATOMS • Smaller particles of matter called quarks exist, but scientists still consider atoms the basic building blocks of matter. • Quark – smaller particles that make up protons and neutrons – 6 quarks are known to exist

16. MASSES OF ATOMS • Atomic Mass – composed mostly of protons and neutrons in the nucleus – also called MASS NUMBER • Atomic Number – the number of PROTONS in an atom; number of PROTONS also identifies the element • In neutral atoms – PROTONS ALWAYS EQUAL ELECTRONS!!!! • To find the number of NEUTRONS of an atom: # of neutrons = mass number (atomic mass) – atomic number (in other words – take the difference between the 2 numbers in the element box!)

17. MASSES OF ATOMS • Average Atomic Mass – weighted average mass of an element • Measured in amu’s – Atomic Mass Units • This is why the atomic mass is listed as a DECIMAL on the Periodic Table!

18. MASSES OF ATOMS • DRAW THIS  2-4 Electron Configuration

19. Answer the EQ: What is the difference between atomic number & atomic mass? (TOP LEFT) Atomic number identifies the element and consists of protons only. Atomic mass is the combination of protons and neutrons. Once you have answered, please come pick up a green quarter sheet and fill in the table. Pg. 41 in IAN

20. October 4, 2017 Please come in… • Pick up a blue sheet of paper from the front. • CHOOSE 2 TO COMPLETE. You will have 10 minutes to complete. I will check for completion. • Tape on page 43. (Don’t use the whole page, we will tape something else on it as well.) • If you finish early…please start looking at your periodic table and begin memorizing #1-18.

22. October 4, 2017 Housekeeping • I will be out tomorrow. Please be on your best behavior. • We will have a quiz on Friday. Tomorrow’s MAV block will have options for you to go and review. • Some of you may receive a stamp today. • For your quiz…study your colored “mini” quizzes and your element tile…you should be good.

23. EQ: What do elements in the same group have in common? (TOP) • Title your page: THE PERIODIC TABLE • Please put on page 42 in IAN

24. THE PERIODIC TABLE • Periodic Table – table where elements are organized by increasing ATOMIC NUMBER (number of protons) • In the late 1800’s, Dimitri Mendeleev devised the first periodic table based on ATOMIC MASS – however, some elements were out of order. • In 1913, Henry Moseley arranged elements by ATOMIC NUMBER and is what we use today.

25. THE PERIODIC TABLE • The Periodic Table is arranged by GROUPS and PERIODS. • GROUPS – VERTICAL columns of elements with similar properties – groups are numbered 1-18. • Elements in the same GROUP have the same number of ELECTRONS in their outer energy level – these are called VALENCE ELECTRONS and they determine how an element bonds.

26. THE PERIODIC TABLE • PERIODS – HORIZONTAL rows of elements that contain increasing numbers of protons and electrons. Periods are numbered 1-7. • Each period-row ends when the outer energy level is filled (magic number is 8!). • As you move from LEFT to RIGHT across the periods/rows – elements become LESS metallic.

27. Please pick up: • a salmon colored quarter sheet (pg. 43 in IAN- same as your blue half sheet) • 2 white sheets (pg. 44 and 45 in IAN) • Work on these and have completed by Friday.

28. Luke, because there’s no power (it’s during a blackout). Dark Halloween Night On a dark, stormy Halloween night, four kids named Luke, John, Sarah and Bob walk into a haunted house during a blackout. Only one can escape. They take a staircase to the second floor, a trapdoor on the left, then go up the ladder to the right, followed by a 28-foot slide to the basement through the mouth of a Giant Panda. In one corner of the murky cellar is a chainsaw, a dagger, a rope with a noose and an electric chair. Written on the wall in blood are the words, “Only one will survive – choose your death!” Bob takes the rope, Sarah picks up the dagger, John chooses the chainsaw and Luke uses the chair. WHO SURVIVES??? (explain why)

29. Housekeeping • We will have a Quiz on Thursday  • Over Periodic Table and metals, nonmetals, and metalloids. • You will receive more info Wed, it’ll be over 2 pink sheets. • I’m still missing a bunch of Poster Projects. I put in the 0’s and it dropped grades a couple of points… • Make Ups!!! Please get things from your folder AND schedule times to make up quizzes& Tests!

30. DATA TALK QUIZ RESULTS  4TH 86% 5TH 86% 6TH 90% 7TH 92% 8TH 86% OVERALL 88%

31. Pgs. 42-50 DUE TUESDAY (TOMORROW)Whole Packet due FRIDAY • Please pick up a white periodic table from the front. You will need a yellow, a blue, and a green colored pencil (or crayon). • Please tape this on pg. 46 in IAN. • When you finish coloring, please pick up a blue element sheet and fill out. Pg. 47 in IAN • Then you will be working on your Periodic Table packet

32. Bellringer…10/11 • How was the first periodic table arranged? What was the problem with the first arrangement? • What do elements in the same group have in common? • What do elements in the same period have in common? • How many groups and how many periods make up the periodic table? • First arranged by mass. It was out of order. • They have the same number of electrons in the outer shell. • All the elements in a period have the same number of electron shells. They also read left to right, meaning the protons increase as you go. • 18 groups, 7 periods.

33. EQ: Which of the following would be the best conductor – iodine, silver, silicon, or sulfur? (TOP) • Title your page: METALS, NONMETALS, & METALLOIDS • We will begin notes on pg. 48, if you need to continue go to the back on pg. 49

34. METALS, NONMETALS, & METALLOIDS • METALS – good conductors of heat and electricity – all but MERCURY are solid at room temperature. • METALS are located to the LEFT of the zig-zag (staircase) • ALKALI METALS – (Group 1) are the MOST reactive of all metals; don’t occur in nature in their element form (always found in a compound) • ALKALINE EARTH METALS – (Group 2) shiny, ductile, and malleable; combine with other elements • TRANSITION METALS – (Groups 3-12) most familiar metals because they often occur in nature uncombined • LANTHANIDE SERIES – elements #58-71 (not special – at bottom due to spacing!) • ACTINIDE SERIES – elements #90-103 (not special – at bottom due to spacing!)

35. METALS, NONMETALS, & METALLOIDS 7. NONMETALS – elements that are usually gases or brittlesolids at room temperature; most can form ionic and covalent compounds (more on that in the NEXT unit) – located to the RIGHT of the zig-zag (staircase) 8. Halogens – (Group 17)MOST reactive non-metals! These elements combine with Group1 to form salts! 9. NOBLE GASES – (Group 18) – exist as isolated atoms. They are all STABLE because outer energy level is FULL (magic # is 8 – except for He - which is 2!) 10. HYDROGEN– ONLY nonmetal located to the LEFT of the zig-zag (staircase). Located at the TOP of Group 1 because of reactivity AND it has ONE Valence Electron!

36. METALS, NONMETALS, & METALLOIDS • METALLOIDS – are part of the mixed groups (Groups 13-17) – therefore they can be metals, nonmetals, & metalloids. • Actually TOUCH the zig zag (staircase) • Have qualities of metals & nonmetals • Also know as SEMI-CONDUCTORS • Used WIDELY in modern technology

37. ANSWER THE EQ: Which of the following would be the best conductor – iodine, silver, silicon, or sulfur? (TOP LEFT) • Please come up and grab a pink mini quiz. • Put this on pg. 47 with your blue element sheet.
