On the BOARD The following information will be on the board for each molecular model: 1.The model 2.The name of the molecule 3.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 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. 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 7A B = 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 = Fluorine B = Carbon
STEP 3 Write the atomic symbol of each atom P = Fluorine B = Carbon
STEP 3 Write the atomic symbol of each atom P = Fluorine B = Carbon
STEP 3 Write the atomic symbol of each atom P = Fluorine = F B = Carbon = C
Step 3 In the Third Box… P = Fluorine = F B = Carbon = C
BUILD THE MODEL Build the Model It 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.
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, 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, everything must be filled, nothing can be empty. 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 = F B = 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 first Hydrogen goes second
STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third
STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third then 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 CF 4
STEP 5 In the Fifth Box… CF 4
STEP 6 Draw each atom in the molecule ONCE!
STEP 6 Draw each atom in the molecule ONCE!
STEP 6 Draw each atom in the molecule ONCE!
STEP 6 Draw each atom in the molecule ONCE! Draw C and F ONCE!!!!!!!!!
STEP 6 Draw each atom in the molecule ONCE! Electrons!!!
STEP 6 Draw each atom in the molecule ONCE! Use the correct electron Identify each atom with its atomic symbol
STEP 6 Draw each atom in the molecule ONCE! Use the correct electron. Identify each atom with its atomic symbol.
STEP 6 In the Sixth Box…
STEP 7 DRAW the molecule WITH electrons.
STEP 7 DRAW the molecule WITH electrons. Make sure every atom is HAPPY.
STEP 7 DRAW the molecule WITH electrons. Make sure every atom is HAPPY. Every atom needs 8 electrons in its LAST energy level…
STEP 7 DRAW the molecule WITH electrons. Make sure every atom is HAPPY. Every atom needs 8 electrons in its LAST energy level… EXCEPT Hydrogen that needs 2
STEP 7 DRAW the molecule WITH electrons. Make sure every atom is HAPPY. Every atom needs 8 electrons in its LAST energy level… EXCEPT Hydrogen that needs 2 8 and 2, magic numbers, happy atoms have a magic number of electrons in their last energy level.
STEP 7 DRAW the molecule WITH electrons. Make sure every atom is HAPPY. Every atom needs 8 electrons in its LAST energy level… EXCEPT Hydrogen that needs 2 8 and 2, magic numbers, happy atoms have a magic number of electrons in their last energy level. Every connector, small or big, represents a SHARED PAIR of ELECTRONS!
STEP 7 Every connector, small or big, represents a SHARED PAIR of ELECTRONS! Atoms share electrons to be HAPPY
STEP 7 Every connector, small or big, represents a SHARED PAIR of ELECTRONS!
STEP 7 Every connector, small or big, represents a SHARED PAIR of ELECTRONS! One electron from Carbon one from Fluorine
