Modeling Molecules

Introduction:

You can represent a molecule two-dimensionally, as a structural formula or electron dot structure. Although such models are useful in certain contexts, they do not accurately represent bond angles between atoms or shapes of molecules. In this activity, you will construct three-dimensional models of several molecules. You will use electron dot structures and structural formulas to inform how you construct the three-dimensional models.

Materials:

Google
Microsoft Word
Paint (the computer tool)

Procedure:

1. Identify the chemical and structural formulas and electron dot structures of the following molecules:

water, ammonia, carbon dioxide,

Why?

It would make the most sense to use the electron dot structure. This one should be used because it shows the number of electrons that fluorine has, it also shows that fluorine has an unpaired electron. I know that fluorine has 7 valence electrons. Fluorine really wants to gain one more electron to become a noble gas, which means that it is willing to do just about anything to achieve that. That is why fluorine is so reactive; it will react with a lot of
