1. WARM UP
“We never touch people so lightly that we do not leave a trace.”
–Peggy Tabor Millin
What does this mean to you?
How might this impact the way you think about Chemistry, school in general, or the future?

2. Introduction to Chemical Bonding

3. Lewis Dot Diagrams Gilbert Lewis
Show valence electrons (s and p subshells)
Related to group number

4. Lewis Dot Diagrams
Unpaired e-
Alone on a side

5. Lewis Dot Diagrams To write: Element symbol Dots for e-
4 sides, cover all before pairing

6. Octet Rule Atoms want to be isoelectronic with noble gases
8 valence e- (except He has 2)

7. Octet Rule Atoms will gain, lose, or share valence e to get to 8
Ex: F gains 1, Be loses 2, N shares 3

8. WRAP UP
Use the octet rule to describe why atoms gain/lose/share electrons.
