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
