  1. Bohr Model 11/19/12

  2. Today’s Game Plan

  3. Bell Ringer Infer how you think an atom could become charged using your knowledge of atomic structure from yesterday. **Get your agenda book out after you complete your Bell Ringer** OBJECTIVE S.W.B.A.T apply the bohr model to charged atoms (ions)

  4. 3 MINUTES LEFT!

  5. Bell Ringer Infer how you think an atom could become charged using your knowledge of atomic structure from yesterday. **Get your agenda book out after you complete your Bell Ringer** S.W.B.A.T apply the bohr model to charged atoms (ions) OBJECTIVE

  6. 1 MINUTE LEFT!!!

  7. Bell Ringer Infer how you think an atom could become charged using your knowledge of atomic structure from yesterday. **Get your agenda book out after you complete your Bell Ringer** S.W.B.A.T apply the bohr model to charged atoms (ions) OBJECTIVE

  8. 30 SECONDS LEFT!

  9. Bell Ringer Infer how you think an atom could become charged using your knowledge of atomic structure from yesterday. **Get your agenda book out after you complete your Bell Ringer** S.W.B.A.T apply the bohr model to charged atoms (ions) OBJECTIVE

  10. Week Agenda Monday: Bohr Model Tuesday: Bohr Model with Ions Wednesday: Constructing an Atom Activity Thursday: Happy Thanksgiving! No School! Friday: No School!

  11. Group Norms • Be Engaged! (Off Cell Phones, Heads Up, Answering Questions) • Mistakes are Welcome! • Be Respectful (Speak politely to peers and teachers!) • Use Time Preciously! (Be Efficient, Keep Up)

  12. Today’s Game Plan

  13. Objective: • S.W.B.A.T apply the bohr model to charged atoms (ions) Homework: • BOHR MODEL with ions PROBLEM SET ANNOUNCEMENTS QUIZZES MUST BE FINISHED OR MADE UP BY TUESDAY AFTER SCHOOL!! IF I DON’T HAVE A SCIENCE FAIR IDEA BY WEDNESDAY, I WILL ASSIGN YOU A PROJECT ALL HOMEWORK MUST BE WRITTEN IN AGENDA BOOKS. MAKE SURE YOU HAVE YOURS EVERY DAY!

  14. Today’s Game Plan

  15. Bell Ringer Infer how you think an atom could become charged using your knowledge of atomic structure from yesterday. **Get your agenda book out after you complete your Bell Ringer** S.W.B.A.T apply the bohr model to charged atoms (ions) OBJECTIVE

  16. Today’s Game Plan

  17. Let’s Talk About Valence Electrons • What are Valence Electrons? • What’s the Octet Rule? • Electrons in the outer most shell • Determine elements chemical properties • Atoms gain, lose, or share electrons in order to have 8 valence electrons How do valence electrons effect an elements reactivity?

  18. Today’s Game Plan

  19. Let’s Try It Together!!

  20. Collaborate! Work With A Partner!

  21. Today’s Game Plan

  22. Exit Ticket • Silently Complete your Exit Ticket/Reflection. You have 5 minutes • When finished raise your hand for Ms. Durrette to collect it • Keep your Cornell Notes out, we have a few more notes to take!

  23. Today’s Game Plan

  24. Charged Atoms • What is an ion? • How is the Octet Rule related to ions? • An atom or bonded group of atoms with positive (+) or (-) charge • Atoms gain or lose electrons to try to have 8 valence electrons • They want to be like Noble Gases

  25. Let’s Talk About Valence Electrons • How do atoms lose and gain electrons? • What are Cations and Anions • Elements on the leftside of the Periodic Table (Groups IA, IIA, IIIA) will tend to lose valence electrons. • End up with a Positive charge= Cations • Elements on the rightside of the Periodic Table (Groups VA, VIA, VIIA) will tend to gain valence electrons • End up with a Negative charge= Anions Cations and Anions attract each other
