  1. ATOMIC CONCEPT SEPTEMBER 28, 2015

  2. DO NOW– 9/28/2015 • You are silent and seated • In your notebook, answer the following: • Q1: What does the atomic number identify? • Q2: Which scientists discovered the electron shells? • Q3: What are the valence electrons? • You have 3 minutes.

  3. REMINDER • SAVE THE SCIENTIST PERFORMANCE TASK DUE TOMORROW VIA GOOGLE DRIVE • QUIZ 4 THIS FRIDAY • NOTEBOOK CHECK THIS FRIDAY

  4. NOTEBOOK CHECK • REGENT PERIODIC TABLE • ATOMIC TIMELINE • DO NOW FOR 9/28 • DO NOW FOR 9/30 • DO NOW 10/1 • COMPLETED QUESTIONS TO CONSIDER QUIZ 4

  5. QUIZ 3 • QUIZ 3 TUTORING • TUESDAY – 4TH PERIOD OR 8TH PERIOD • QUIZ 3 RETAKE • WEDNESDAY AFTERSCHOOL FROM 2:40 PM – 3:15 PM • QUIZ 3 MAKEUP • WEDNESDAY AFTERSCHOOL FROM 2:40 PM – 3:00 PM

  6. AIM • WHAT CAUSES COLOR IN FIREWORKS?

  7. QUESTIONS TO CONSIDER • In-class folder • You should be able to answer all of these questions by Friday Quiz • Paste to notebook

  8. ELECTRON CONFIGURATIONS

  9. GROUND STATE • ELECTRON CONFIGURATION IN THE LOWEST ENERGY STATE. • THIS IS WHAT IS REFLECTED ON THE PERIODIC TABLE

  10. ELECTRON CONFIGURATION • Representation of the arrangement of electrons distributed among the electron shells

  11. BOHR MODEL

  12. WHAT DOES IT MEANS? • CARBON HAS AN ELECTRON CONFIGURATION OF 2-4 • NUMBER OF SHELLS • WHAT PERIOD • THE NUMBER OF VALENCE ELECTRONS • THE NUMBER OF ELECTRONS • THE NUMBER OF PROTONS • THE ATOMIC NUMBER • WHICH SHELL HAS THE HIGHER ENERGY

  13. EXCITED STATE • NOT ALL - ELECTRONS ARE IN THEIR LOWEST ENERGY STATE • EXAMPLE: • 2-4 GROUND STATE • 1-5 EXCITED STATE

  14. YOU TRY IT

  15. WHY THE CHANGE IN STATE? • WHEN ELECTRONS ABSORBED ENERGY, ELECTRONS JUMP FROM GROUND STATE TO EXCITED STATE. • FROM LOWER ENERGY STATE TO HIGHER ENERGY STATE.

  16. EXCITED STATE TO GROUND STATE • THE EXCITED STATE IS A TEMPORARY STATE. • WHEN ELECTRONS MOVE FROM EXCITED STATE TO GROUND STATE, SPECIFIC AMOUNT OF ENERGY IS EMITTED • ELECTRONS MOVE FROM HIGHER ENERGY STATE TO LOWER ENERGY STATE • EMITTED ENERGY IS SHOWN AS COLORS

  17. COLOR RELEASED • THE COLOR EMITTED OR RELEASED DEPENDS UPON WHAT ELEMENT WAS INVOLVED. • THIS COLOR IS ALSO KNOWN AS THE BRIGHT LINE SPECTRUM

  18. FIREWORK VIDEOS • Youtube video and PBS video • http://www.pbslearningmedia.org/asset/phy03_vid_fireworkcol/

  19. AIM • WHAT CAUSSES THE COLOR IN FIREWORKS?

  20. CLAIM

  21. EVIDENCE

  22. REASONING

  23. CER-01 • IN THE REFERENCE FOLDER – RUBRIC AND EXAMPLE • IN THE IN-CLASS FOLDER – TAKE OUT CER-01 • SILENTLY RESPOND TO THE AIM PROMPT • YOU HAVE 5 MINUTES • THIS IS TO BE TURN IN TO AT END OF CLASS

  24. SUMMARY: TODAY LESSON

  25. HOMEWORK REMINDER • Save the Scientist Performance Task is due tomorrow. Make sure you submit it via Google Drive by no later than 5PM
