STEP 1
• Build the Model
STEP 1
• Build the Model• It only fits one way
STEP 1
• Build the Model• It only fits one way• It must be complete, everything must be filled,
nothing can be empty.
STEP 1
• Build the Model• It only fits one way• It must be complete, everything must be filled,
nothing can be empty.• There are NO RINGS in this lab.

• ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO! When you can’t build the molecule without them.
STEP 1
• ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO!
• When you can’t build the molecule without them.
STEP 2
• Identify the Atoms in the molecule using the Periodic Table
STEP 2
• Identify the Atoms in the molecule using the Periodic Table
STEP 2
• Identify the Atoms • in the molecule using the Periodic Table
STEP 2
• Identify the Atoms • in the molecule • using the Periodic Table
STEP 2
• Identify the Atoms
PPBPP Carbon TetrafluorideP = 2 – 7AB = 2 – 4A
STEP 2
• Identify the Atoms
Carbon TetrafluorideP = 2 – 7AB = 2 – 4A
STEP 2
• Identify the Atoms
P = 2 – 7AB = 2 – 4A
STEP 2
• Identify the Atoms
P = 2 – 7AB = 2 – 4A
Period Number – Family Number
STEP 2
• Identify the AtomsP = 2 – 7A = Fluorine
STEP 2
• Identify the AtomsB = 2 – 4A = Carbon
STEP 2
• Identify the Atoms
P = 2 – 7A = FluorineB = 2 – 4A = Carbon
STEP 3
• Identify the atomic symbol of each atom
P = 2 – 7A = FluorineB = 2 – 4A = Carbon
STEP 3
• Identify the atomic symbol of each atom
P = 2 – 7A = FluorineB = 2 – 4A = Carbon
STEP 3
• Identify the atomic symbol of each atom
P = 2 – 7A = Fluorine = FB = 2 – 4A = Carbon = C
Step 3
Fluorine = F Carbon = C
STEP 4
• Draw the molecule. • Identify each atom with its atomic symbol
STEP 4
• Draw the molecule. • Identify each atom with its atomic symbol• NEATNESS COUNTS!
THE SHAPE IS VERY IMPORTANT!!!!
STEP 4
• Draw the molecule.
• Identify each atom with its atomic symbol
STEP 4
P = Purple = 2 – 7A = Fluorine = FB = Black = 2 – 4A = Carbon = C
STEP 4
P = Purple = Fluorine = FB = Black = Carbon = C
STEP 4
STEP 5
• Write the chemical formula of the molecule.• There is an order to the chemical formula…..
STEP 5
• There is an order to the chemical formula…..Carbon goes first
STEP 5
• There is an order to the chemical formula…..Carbon goes firstHydrogen goes second
STEP 5
• There is an order to the chemical formula…..Carbon goes firstHydrogen goes secondOxygen goes third
STEP 5
• There is an order to the chemical formula…..Carbon goes firstHydrogen goes secondOxygen goes thirdthen Everything Else!
STEP 5
• There is an order to the chemical formula…..• Carbon…Hydrogen…Oxygen…Everything Else!• You must count each type of atom and write
its subscript number.
STEP 5
• There is an order to the chemical formula…..• Carbon…Hydrogen…Oxygen…Everything Else!• You must count each type of atom and write
its subscript number.
STEP 5
• There is an order to the chemical formula…..• Carbon…Hydrogen…Oxygen…Everything Else!• You must count each type of atom and write
its subscript number.• SIMPLE RULE…never write 1 as a subscript
number
STEP 5
• There is an order to the chemical formula…..• Carbon…Hydrogen…Oxygen…Everything Else!• You must count each type of atom and write its subscript
number.• SIMPLE RULE…never write 1 as a subscript number• One carbon and four fluorines…no oxygen or hydrogen
