BOND TYPES AND LEWIS DOT
STRUCTURES NOTES
Lewis Dot Structures
 Used to predict and show structural
arrangements of molecules
 Shows how electrons being shared in
covalent bonds
 Follows Octet Rule
 Example
Lewis Dot Structures, pg 2
 can substitute lines for pairs of shared
electrons
 examples
Steps for Lewis Dot Structures
1. Determine number of valence electrons for
each element
2. Determine central atom (atom with lowest
electronegativity)
3. Write central atom and valence electrons
4. Fill in remaining elements with their valence
