The Molecular Model Lab

Number

Start with the NUMBER of the Model.

• If you are starting at 1…• The person next to you is starting at 10

NumberIf you are starting at 1, your order is…

• 1 (must be signed by Mr. Gussin)• 2• 3 (must be signed by Mr. Gussin)• 4• 5 (must be signed by Mr. Gussin)• 6• 7• 8• 9• 10 (Show Mr. Gussin before you go on to EXTRA CREDIT)

NumberIf you are starting at 10, your order is…

• 10 (must be signed by Mr. Gussin)• 9• 8 (must be signed by Mr. Gussin)• 7• 6 (must be signed by Mr. Gussin)• 5• 4• 3• 2• 1 (Show Mr. Gussin before you go on to EXTRA CREDIT)

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

In the first box write…

The model PPBPP

STEP 1

In the first box write…

The model PPBPP • P = Purple • B = Black

STEP 1

In the first box write…

The model PPBPP • P = Purple • B = Black

B is always BLACK. There is NO BLUE in this lab until the EXTRA CREDIT. NO BLUE in Models 1 through 10!

STEP 1

In the first box write…

The model PPBPP

and

The name of the molecule Carbon Tetrafluoride

STEP 1

In the First Box…

PPBPP Carbon Tetrafluoride

STEP 2

In the second box write…

The location of the atoms in the molecule.

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

STEP 2In the second box write…

The location of the atoms in the molecule.

• 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

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.

BUILD THE MODEL

• Build the Model• It only fits one way• It must be complete,

• ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO!

BUILD THE MODEL

• ONLY USE THE LONGER CONNECTORS WHEN YOU HAVE TO!

• 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
