3. REMINDER SAVE THE SCIENTIST PERFORMANCE TASK DUE TODAY VIA GOOGLE DRIVE BY 5PM QUIZ 4 THIS FRIDAY NOTEBOOK CHECK THIS FRIDAY

4. QUIZ 3 QUIZ 3 TUTORING ◦ TODAY – 4 TH PERIOD OR 8 TH 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

5. AIM Which mystery element has an electron configuration of 2-8-16-2 in its ground state?

6. PRE-LAB Q1: What is the maximum numbers of electrons in Energy Level 1 (shell)? ___________________

7. PRE-LAB Q2 If the electron configuration is 2-8-4: ◦ How many energy levels does the element have? ◦ What is the total number of electrons? ◦ What is the maximum number of electrons in the outside shell?

8. GROUND STATE ELECTRON CONFIGURATION CARBON ◦ ELECTRON CONFIGURATION ◦ NUMBER OF SHELLS ◦ DIAGRAM ◦ TOTAL NUMBER OF ELECTRONS

9. GUIDED PRACTICE SODIUM ◦ ELECTRON CONFIGURATION ◦ NUMBER OF SHELLS ◦ DIAGRAM ◦ TOTAL NUMBER OF ELECTRONS

10. INDEPENDENT PRACTICE DO THE SAME FOR CALCIUM, NEON AND SILICON YOU HAVE 5 MINUTES

11. CALCIUM ◦ ELECTRON CONFIGURATION ◦ NUMBER OF SHELLS ◦ DIAGRAM ◦ TOTAL NUMBER OF ELECTRONS

12. NEON ◦ ELECTRON CONFIGURATION ◦ NUMBER OF SHELLS ◦ DIAGRAM ◦ TOTAL NUMBER OF ELECTRONS

13. SILICON ◦ ELECTRON CONFIGURATION ◦ NUMBER OF SHELLS ◦ DIAGRAM ◦ TOTAL NUMBER OF ELECTRONS

14. DEMONSTRATION EVERY ONE USE THE ELECTRON SHELL SHEET AND DO THE ELECTRON DISTRIBUTION FOR ◦ O ◦ Li ◦ K ◦ Al ◦ B ◦ Cl

15. THE SCIENCE Where can I find information about an atom’s electron configuration? What are valence electrons? How can I tell how many electron shells exist for an atom based on the electron configuration? If I have the electron configuration, how can I determine number of electrons and protons?

16. CRITICAL THINKING ALRIGHT NOW BACK TO TODAY AIM ◦ DO QUESTION 3 (PARTS A, B, AND C) TO RESPOND TO THE AIM ◦ THIS IS SILENT AND INDIVIDUAL WORK ◦ YOU HAVE 5 MINUTES

17. SUMMARY: TODAY LESSON
