Presentation Transcript

  1. Catalyst 11/14/12 • Consider Phosphorus. • How many protons does it have? • How many neutrons does it have? • How many electrons does it have (when neutral)? 2. Draw a generic model of an atom and label its parts. Indicate the charges of each subatomic particle.

  2. Agenda 11/14/12 • Catalyst • Announcements • Organizing Binders • How to Create QuickStudy Guides • Bohr Model Lesson • Class Practice • Exit Slip • Recognition of Achievements

  3. Announcements Continued • Unit#2 Make Up Exams – Must be done by Friday. (Schedule a time.) • Alternative Assignment to Atomic Theory Presentations (Posted on Edmodo) • Grade/Attendance Change Forms • Include original assignment • Leave inside bin • No grade changes will be discussed during class (email only or private conference outside of class time)

  4. Announcements Continued • Using Class Cash and Emergency Passes for Extra Credit • Write your name on a piece of paper and wrap it around your class cash • Class Cash: 5 points extra credit to exam of your choice (except benchmark) • Emergency Passes • Tutoring is available during 7th (student cafeteria), 9th, 10th periods AND after school (in room 22)

  5. Atomic Theory Presentations • Keep it positive. (No name calling or negative comments.) • Stay focused. (Avoid side conversations) • Ask questions at the end. • Take notes! You’ll need this at the end.

  6. Class Points P3: 13 pts P4: 9 pts P6: 14 pts Your class can earn class points if: everyonein class: Comes to class quietly and on time Stays focused and on task during class Leaves classroom neat and organized Students are teaching other students Majority of class participates Follows all classroom expectations and procedures And more…

  7. Your Binder Should Have • The SIDE and FRONT of your binder should have your last name and first name like this “Rodriguez, John.” • Table of Contents • Tabs (Didn’t buy dividers? Use construction paper to make dividers.) • Packets (only graded packets) • Quizzes • Exams • Lab • Reference Sheets

  8. Table of Contents • One main table of contents as your first page • Inside the Packets section, you should have at least 2 Unit Table of Contents. • Use your graded packets, quizzes, and exams to fill in the blanks

  9. Binder Expectations • Must be organized • Used as a reference • May take home or leave in class (your choice) • Will be given a final project grade at the end of the school year (DO NOT LOSE IT.) • Updated on a regular basis (I’ll tell you in advance)

  10. Quick Study Sheets • Helps you consolidate information • Helps you organize concepts and procedures • Extra Credit (10% additional points for packet of your choice) • Will be required in the future

  11. How to Make a Quick Study Sheet • Have your packet (and textbook, if available) as your reference • Summarize all information from one unit into one sheet using your OWN words (sometimes less is more) • Label each section of the unit clearly • Have examples for math based problems

  12. Class Action Plan • Wednesday - Bohr Model Practice • Thursday - Isotopes • Friday - Review of Units #1 - #3 • Friday After School – Benchmark Review Session (bring your own questions)

  13. Objective • SWBAT describe the Bohr Model of the Atom and draw a Bohr model of the atom given its atomic number.

  14. What does the inside of an atom look like?

  15. Bohr Model of Carbon Atom

  16. Subatomic Particles – What’s in an atom?

  17. IMPORTANT • The number of PROTONS determines the IDENTITY of the ELEMENT. That is, the reason that carbon is carbon is because of the fact that it has 6 protons. The other subatomic particles does not change the atom’s identity.

  18. Why is this important? Understanding how electrons are arranged in an atom can help us predict how CHEMICAL REACTIONS will happen.

  19. Check For Understanding • Draw a model of an atom and label its parts on Notability (or whiteboard app).

  20. Bohr Model of the Atom • Electrons are found in orbits that circle the nucleus similar to a planet in the solar system orbiting the sun. • The farther the orbit is from the nucleus, the higher the energy of the electron. • This model is NOT completely correct. The current accepted model is the Quantum Model.

  21. Bohr Model of the Atom

  22. Energy Levels • Level 1 = 2 electrons • Level 2 = 8 electrons • Level 3 = 18 electrons • Level 4 = 32 electrons

  23. How to draw a Bohr Model of the Atom • Draw the nucleus with correct number of protons and neutrons • Draw each energy level as needed (i.e. don’t draw all four levels if you don’t need them, as in for hydrogen) • Each energy level must be filled before filling the next energy level • Each energy level can only hold a certain number of electrons • Level 1 = 2 electrons, level 2 = 8 electrons, Level 3 = 18 electrons, Level 4 = 32 electrons

  24. Info You Need • Pieces of information I need to make a Bohr model: • Number of Protons • Number of Electrons • Number of Neutrons

  25. How to Get Info • # of Protons = Atomic # • # of Neutrons = Mass # - Atomic # • # of electrons = # of Protons = Atomic # (in a NEUTRAL atom) • Mass# = Atomic # + # of Neutrons

  26. During Classwork Time • Stay focused on the assignments you are given. • Do the questions INDEPENDENTLY (on your own). • Keep the noise level down. • Ask THREE before you ask ME. • You may put earphones on and listen to music quietly as you do your work. • You must finish a certain number of questions (depends on the person) by the end of the period. DO NOT FORGET YOUR STAMPS! You cannot get them once you leave the class.

  27. Exit Slip 11/14/12 • QUIETLY and INDEPENDENTLY answer the following on Notability and email it to gutierrezbr@elizabeth.k12.nj.us with “p4 (or p6) ES 11/14” on the subject line. I must receive it by the end of the period. If you are talking or copying, you will not receive credit. • 1. Draw a Bohr model of Magnesium.

  28. Recognition of Achievements Students who receive at least an 80% or higher on an exam will be recognized. These will eventually be posted on the wall. • Bachelor of Science (Sc.B.) • Master of Science (M.Sc.) • Doctor of Philosophy (PhD)

  29. Bachelor of ScienceReceived 80 – 85% on either Unit 1 or 2 Exam Period 4 • Monica S. Period 6 • Nataly P. Period 3 • Edgard G. • Takumi H.

  30. Master of ScienceReceived 86 – 92% on either Unit 1 or 2 Exam Period 4 • Wesley P. • Diego R. • Muhammad S. Period 6 • Wiljeamps S. • Sabrina Difo Period 3 • Melissa M. • Julian S. • Anton V. • Daniel S. • Jazmine R

  31. Doctor of PhilosophyReceived 93% or higher on either Unit 1 or 2 Exam Period 6 Period 3 • Michelle Q. • Pathani C. • Dienuel C. • Iryn F. Period 4

  32. “Genius is 1% inspiration and 99% perspiration.” –Thomas Edison
