Minimum Days on Tuesday and Thursday of this week– 12:10 Dismissal 5. Power Notes- Bohr Model Drawings Colored Pencils, Highlighters or Markers- must highlight notes; Periodic Table 6. Review and Reflect on Page One Only
- 3. 1) Put your name, date and period at the top of the page. 2) Fold you paper in half 3) Left Column Title: What Went Well 4) Reflect on the cooperative experience; what positive things did you hear, feel, see by working in a group. 5) Please write a minimum of 3 things that went well in your group.
- 4. 1) Right Column Title: What Could Go Better 2) Reflect on the cooperative experience; without naming names, what things did you hear, feel, or see in your group that did not go well. 3) Please write a minimum of 3 things that could have gone better. 4) We only have control of how we respond, what could have been done to improve the situation?
- 5. Capture in 5-6 sentences: 1) I feel cooperative groups………. 2) In my life I know I will need to depend on other to ……………. 3) I also know people will respond to me based on …………… 4) In a cooperative group it is always important that ……….. 5) I don’t understand or I do understand why cooperative groupings are important because ……….. Highlightthe starters

- 7. Bohr Model Drawings The concept of elements has been around since ancient times. We now know that each element has its own unique number of protons. Although each element can have a varying amount of neutrons(isotope) or electrons(ion), its basic characteristics, properties and how it reacts with other elements is basically the same.
- 8. Bohr Model Drawings Neils Bohr is the scientist responsible for the atomic model that looks very much like our solar system. The Periodic Table not only tells us about each individual atom but is also set up to show us how to draw the Bohr Model….well, at least for the first three rows.
- 9. Bohr Model Drawings The Bohr model is helpful in not only understanding the electron configuration but for also understanding why and how some elements will bond with other elements. -Magic # is 8, -Magic # is 2 for H and He
- 10. Bohr Model of Carbon Atomic # = Protons “+” and Electrons “-” if neutral Atomic Mass = Sum of Protons and Neutrons
- 12. Valence and the Periodic Table Example: 1. The columns or families each element is located in tells you the number of valence electrons for families 1, 2…..13,14,15,16,17 and 18 - Elements in Family 1 have 1 valence electrons - Elements in Family 2 have 2 valence electrons - Elements in Family 13 have 3 valence electrons 2. The pattern continues up to Family 18 3. The pattern DOES NOT occur for the Transition elements (short columns) Transition Elements REVIEW Remember: Metals give away their electrons, while nonmetals
- 13. Basic Configuration Example: 1.The Periodic Table Connections – 1st 3 rows only -Rows = # of shells or levels around the nucleus -# of elements in each row = # of electrons found on that level Row 1 = 1 shell around nucleus; maximum of 2 electrons on shell Row 2 = 2 shells around nucleus; maximum of 8 electrons on shell Row 3 = 3 shells around nucleus; maximum of 8 electrons on shell
- 14. Lewis Dot Diagrams Example: Beryllium is in Family #2 1. Illustrated using elements Chemical Symbol and DOTS to represent its’ VALENCE electrons. 2. Beryllium has a VALENCE of 2 Be 1 2 3 4 5 6 7 8
- 15. Drawing the Bohr Models and Lewis Dot Diagrams 1. Locate the element on the P.T. 2. Record the info about the element. 3. Draw the nucleus and write the # of each type of subatomic particle inside. 4. Draw the correct amount of shells outside the nucleus based on the row # 5. Start loading electrons on the specific shells from the inside out. 6. Remember: YOU MUST load each shell full before moving farther out to the next shell.
- 16. Let’s try a couple: Lithium Row= Protons = Neutrons = Electrons = Lewis Dot 2 3+ 7-3=4 3- P = 3+ N = 4 2- 1- Li
- 17. Let’s try a couple: Magnesium Row= Protons = Neutrons = Electrons = Lewis Dot 3 12 + 24- 12=1212- P = 12+ N = 12 2- 8- Mg 2-
- 18. Let’s try a couple: Oxygen Row= Protons = Neutrons = Electrons = Lewis Dot 2 8+ 16-8=8 8- P = 8+ N = 8 2- 6- O
- 19. Homework 1) Review and Reflect on Page one of Power Notes – Bohr Model Drawings 2)Minimum Day tomorrow – Per. 1,3,4,5,7 3)Binder Check #2- Due Wed.
