Warm up: Electron Config.
Work with your small group to answer these questions
If you are confused, complete steps 1 and 2 before asking for help, then raise your hand
If you finish early, find 1 person who does not understand and explain to them

6. Exit Slip How? What? (5 min)
C – No talking
H – Raise hand
A – Taking exit slip
M – In seat
P – Completing exit slip without notes and turning in
If you finish early, summarize what you learned at the bottom of your notes OR answer today’s guiding question

7. Introduction to Bonding
Objective:
Predict and differentiate between the bonds that will form between two elements
Draw the Lewis Dot Structure for all Group a elements

8. Guiding Question
Why is road salt used to keep roads from icing over?

9. Definition: A bond that exists between a metal and a non- metal; valence electrons are transferred from the metal to the non-metal
Ionic Bond
M + N.M.

10. Covalent Bonds
Definition: A bond between two non-metals; electrons are shared

11. Ionic v. covalent
I Do
You Do
MgCl2
NaF
NO2
CO2
H2O
ZnCl2
K2O
LiCl

12. Lewis dot structure The model we use to demonstrate bonding
Dots represent valence electrons
Follow the Octet Rule: Atoms want 8 valence electrons
Full and balanced at 8
Lewis dot structure

13. Steps to create a Lewis Structure
Write out the atomic symbol and determine the number of valence electrons
Place a dot to represent one valence electron
Continue adding dots clockwise around the symbol; do not pair until 4 single dots have been placed

14. Lewis diagram for Oxygen
Write out the atomic symbol and determine the number of valence electrons
Has 6 valence electrons

15. Lewis diagram for Oxygen
Place a dot to represent one valence electron

16. Lewis diagram for Oxygen
Each consecutive dot should be placed around the symbol in a clockwise fashion

17. Lewis diagram for Oxygen
Only start pairing valence electrons after four single ones have been placed

18. Cl - IONS Draw the Lewis Dot Structure for Cl-1 Remember:
+ = Lose electrons
- = Gain electrons - Cl

19. You try (3 minutes)
Create the Lewis Diagrams for:
Carbon
Argon
S-2

20. Activity: Independent Practice
What?
How?
C – None
H – Raise hand
A – Writing electron configurations
M – None
P – Recoding answers on left page, head up, reading and thinking through all questions, discussing with group
15 minutes  Discuss for 5 minutes  Verify & Review

21. Exit Slip How? What? (5 min)
C – No talking
H – Raise hand
A – Taking exit slip
M – In seat
P – Completing exit slip without notes and turning in
If you finish early, summarize what you learned at the bottom of your notes OR answer today’s guiding question

22. Forgetting to stretch is a bear.
