A. First let's imagine the macroscopic pictures of the 4 test tubes each containing a sample of one of the halogens at room temperature and pressure. What do you think you would you see in each of the 4 test tubes? Do you think that you can distinguish among the four halogen samples by sight alone? Each member of the group should try to draw what they imagine each sample would look like. Discuss the drawings and pick the one that your group will submit to the instructor. B. Now let's think about the microscopic structure of each sample. If you could "see" the molecules, what do you think you would see in each of the test tubes? Each group member should construct a mental picture (model) of what he/she would see at the molecular level in each of the 4 test tubes, then draw the picture and describe it in their own words to the other group members. Again discuss the drawings and descriptions and pick the ones that your group will submit to the instructor.

 construct a mental picture (model) of what you would see at the molecular
level in each of the 4 test tubes, then draw the picture for the macroscopic and microscopic describe it. 

Workshop 2: Models in Chemistry; Part 1. Models in Chemistry: In Chemistry we will spend a lot of time talking about atoms and molecules that we cannot see. It is thus very important to have a mental picture of what these atoms and molecules may look like and how they may behave. These pictures or models need not to be completely accurate in every regard and, in many cases, should not be complex. In fact, the simplest model that is necessary to accurately depict (describe) a phenomenon is often the best model. And to describe a different phenomenon you often will need to employ a different model. With this in mind, we want to start building simple models to help us mentally visualize atoms and molecules. The halogens all exist naturally as diatomic molecules. A diatomic molecule is one that is comprised of 2 atoms joined together by a covalent bond. For example, in nature chlorine does not usually exist as a single Cl atom, rather it exists as a diatomic Clz molecule. At room temperature and pressure, chlorine and fluorine are gases, bromine is a liquid, and iodine is a solid. Imagine that you have a test tube of each of these elements at room temperature and normal pressure. Discuss these questions among your group members: A.
