STEP 1 Identify the Atoms in the molecule using the Periodic Table

STEP 1 Identify the Atoms PPBPP Carbon Tetrafluoride P = 2 – 7A B = 2 – 4A

STEP 1 Identify the Atoms Carbon Tetrafluoride P = 2 – 7A B = 2 – 4A

STEP 1 Identify the Atoms P = 2 – 7A B = 2 – 4A

Period Number – Family Number STEP 1 Identify the Atoms P = 2 – 7A B = 2 – 4A Period Number – Family Number

STEP 1 Identify the Atoms P = 2 – 7A = Fluorine

STEP 1 Identify the Atoms B = 2 – 4A = Carbon

STEP 1 Identify the Atoms P = Fluorine B = Carbon

STEP 2 Identify the atomic symbol of each atom P = Fluorine B = Carbon

STEP 2 Identify the atomic symbol of each atom P = 2 – 7A = Fluorine B = 2 – 4A = Carbon

STEP 2 Identify the atomic symbol of each atom P = 2 – 7A = Fluorine = F B = 2 – 4A = Carbon = C

Step 2 Fluorine = F Carbon = C

STEP 3 Build the Model

STEP 3 Build the Model It only fits one way

STEP 3 Build the Model It only fits one way It must be complete, everything must be filled, nothing can be empty.

STEP 3 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.

STEP 3

STEP 3 Build the Model It only fits one way It must be complete, everything must be filled, nothing can be empty. ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO! When you can’t build the molecule without them.

STEP 3 ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO! When you can’t build the molecule without them.

STEP 4 Draw the molecule. Identify each atom with its atomic symbol

THE SHAPE IS VERY IMPORTANT!!!! 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 = F B = Black = 2 – 4A = Carbon = C

STEP 4 P = Purple = Fluorine = F B = Black = Carbon = C

STEP 4 Purple = F Black = C

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 first Hydrogen goes second

STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third

Remember N doesn’t follow the rules of order, STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third then Everything Else! Remember N doesn’t follow the rules of order, It goes before C and H!

Remember N doesn’t follow the rules of order, STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third then Everything Else! Remember N doesn’t follow the rules of order, It goes before C and H!

STEP 5 There is an order to the chemical formula….. Carbon…Hydrogen…Oxygen…Everything Else! Remember N doesn’t follow the rules of order, It goes before C and H! You must count each type of atom and write its subscript number.

STEP 5 You must count each type of atom and write its subscript number.

STEP 5 ! You must count each type of atom and write its subscript number. SIMPLE RULE…never write 1 as a subscript number

CF4 STEP 5 SIMPLE RULE…never write 1 as a subscript number One carbon and four fluorines…no oxygen or hydrogen CF4
