On the BOARD

The following information will be on the board for each molecular model:

1. The model2. The name of the molecule3. The location of the atoms in the molecule on

the Periodic Table

STEP 1

• The location is the family number and period number from the Periodic Table.

P = 2 and 7A

B = 2 and 4A

STEP 2

In the Second Box…

P = 2 and 7A B = 2 and 4A

STEP 3

Identify the Atoms in the molecule using the Periodic Table.

Write the….• Color• Name• Atomic Symbol

For each atom in the molecule.

STEP 3

Identify the Atoms in the molecule using the Periodic Table.

P = 2 and 7AB = 2 and 4A

Color = Period Number and Family Number

STEP 3

Identify the Atoms

P = 2 and 7A = Fluorine

STEP 3

Identify the Atoms

B = 2 and 4A = Carbon

STEP 3

Identify the Atoms

P = FluorineB = Carbon

STEP 3

Write the atomic symbol of each atom

P = FluorineB = Carbon

STEP 3

Write the atomic symbol of each atom

P = FluorineB = Carbon

STEP 3

Write the atomic symbol of each atom

P = Fluorine = FB = Carbon = C

Step 3

In the Third Box…

P = Fluorine = F B = Carbon = C

BUILD THE MODEL

Build the ModelIt only fits one way

Build the Model

It only fits one way

It must be complete, everything must be filled, nothing can be empty.

• USE THE LONGER CONECTORS WHEN YOU CAN’T BUILD THE MODEL WITHOUT THEM!

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 = Fluorine = FB = Carbon = C

STEP 4

Purple = F In the Fourth Box….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 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
