Atoms form bonds to gain a full shell of
valence electrons. (Octet Rule)
If electrons are not involved in bonding, then
they are lone pairs.
Each bond is made up of 2 electrons.


Count up the total # of valence electrons.
 If it’s an ion, then add or subtract e- as
needed.
Connect all the atoms with single bonds.
Place the remaining electrons as lone pairs
around the atom.
Create double or triple bonds if there are not
enough electrons to go around.
ALWAYS FOLLOW THE OCTET RULE!!!!
