Molecule
Identify the
Central Atom
Number of atoms bonded to
central atom
Number of *non-bonding electron pairs around the central atom
Number of VESPR Groups**
Draw the Lewis structure showing the correct shape. Use element symbols, dots for non-bonding electron pairs and dashes for bonded electrons.
Name the shape.
BeCl2
CO2
HCN
BF3
CH2O
SO2
CH4
NH3
H2O
* The speaker uses the term “lone electron pair” instead of non-bonding electron pair. It is the same thing.
**Number VESPR Groups is equal to the number of atoms bonded to the central atom plus the number of non-bonding pairs.
