  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 demonstrate mastery (80%) on todays quiz!! Homework: • BOHR MODEL PROBLEM SET • LAST WEEKS ASSIGNMENTS • EXTRA CREDIT WORKSHEET 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 BATHROOM PASS POLICY & DEMERIT SYSTEM WILL BE STRICT THIS QUARTER ALL HOMEWORK MUST BE WRITTEN IN AGENDA BOOKS. MAKE SURE YOU HAVE YOURS EVERY DAY!

  14. Today’s Game Plan

  15. Bell Ringer Using your knowledge of subatomic particles and atomic structure, draw a Hydrogen atom. **Get your agenda book out after you complete your Bell Ringer** S.W.B.A.T describe the placement of subatomic particles and diagram atoms using Bohr Model OBJECTIVE

  16. Today’s Game Plan

  17. Topic: Bohr Model Essential Questions: What does an atoms structure look like? How are electrons configured in atoms?

  18. Subatomic Particles Review • What are subatomic particles? • How do we determine the number of Subatomic Particles in an atom? • The parts that make up an atom. • PEN: Protons, Electron, Neutrons • Atomic Number= # of protons & electrons (in a neutral atom) Atomic Mass= #protons + # neutrons Mass # Protons

  19. What is the Bohr Model? • What is the Bohr Model? • Bohr’s Model was used to explain the energy of atoms • Only works for Hydrogen, but is good visualization for atomic structure P+: 1 E-: 1 N0:1-1= 0 nucleus 1p+ e 1 1 Electron Energy Shell

  20. Hydrogen: + -

  21. Constructing a Bohr Model • How do we make a Bohr Model? • Determine # protons & Neutron draw them in inner circle • Determine # Electrons place in energy levels as follows • 1st energy level= 2e- max • 2nd energy level= 8e- max • 3rd energy level= 18e- max LET’S PRACTICE WITH NITROGEN!

  22. Bohr Model Nitrogen-14 • Determine # protons & Neutron draw them in inner circle • Determine # Electrons place in energy levels as follows • 1st energy level= 2e- max • 2nd energy level= 8e- max • 3rd energy level= 18e- max P+ E- N0

  23. Helium:

  24. Lithium:

  25. Beryllium

  26. 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?

  27. Today’s Game Plan

  28. Bohr Model Practice Problems • 1 person passes out worksheet (10 seconds!!) • 1 person reads directions • Ms. Durrettesolves #1: 5 min • Class solves #2: 5 min • With Partner solve #3: 5 min Check with Class • Individually work on #4 5min Raise your hand SILENTLY with questions When complete raise your hand for Ms. Durrette to collect your classwork and get your exit ticket!

  29. Pay Close Attention! How to draw Bohr Models

  30. Let’s Try It Together!!

  31. Today’s Game Plan

  32. Collaborate! Work With A Partner!

  33. Try on Your Own! Raise your hand Silently with Questions!

  34. Today’s Game Plan

  35. Exit Ticket • Silently Complete your Exit Ticket/Reflection • When finished raise your hand for Ms. Durrette to collect it • Get A Head Start On Your Homework! • Extra Credit Opportunity: Complete Bohr Model Practice Worksheet
