22. Step 3 In the Third Box… P = Fluorine = F B = Carbon = C

23. BUILD THE MODEL Build the Model It only fits one way

24. BUILD THE MODEL Build the Model It only fits one way It must be complete, everything must be filled, nothing can be empty.

25. 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.

26. 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.

27. BUILD THE MODEL

28. 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!

29. 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!

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

31. STEP 4 Draw the molecule. Identify each atom with its atomic symbol NEATNESS COUNTS! THE SHAPE IS VERY IMPORTANT!!!!

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

33. STEP 4 P = Fluorine = F B = Carbon = C

34. STEP 4 Purple = F In the Fourth Box…. Black = C

35. STEP 5 Write the chemical formula of the molecule. There is an order to the chemical formula…..

36. STEP 5 There is an order to the chemical formula….. Carbon goes first

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

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

39. STEP 5 There is an order to the chemical formula….. Carbon goes first Hydrogen goes second Oxygen goes third then Everything Else!

40. 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.

41. 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.

42. 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

43. 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
