Summary
In this activity, students construct physical models of molecular shapes. However, students are not told what the preferred arrangements of electron pair domains are. Instead, they derive the arrangements. Students are given the opportunity to conceptualize what is happening when one electron pair domain acts upon another, and to understand how those interactions result in the molecular geometries predicted by VSEPR theory.

In this activity we will learn how to draw Lewis structures, calculate formal charge and examine resonance. We will also observe the Octet rule and exceptions to this rule.
AP Chem. Lewis Dot Structure Worksheet
Write Lewis Dot Structures and calculate the formal charges for the following compounds:
1. SO2 18. H2O2
CO3-2 19. C2H6
NH3 20. CH3OH
CH4 21. C2H4
H2 22. C4H10
HF 23. C2H5OH
H2O 24. ClO-
N2 25. H2S2
Worksheet ? Hybridization
One model to explain bonding in molecules is called the valence bond theory.
It is based on the concept of hybridized molecular orbitals. Atomic orbitals
(s,p,d) are mathematically mixed to form molecular orbitals with defined shapes
and energy levels. In organic chemistry, we need only look at the hybridization of
the one 2s and three 2p orbitals containing the valence electrons of C,O and N.
