During this lab, we learned about Lewis dot structures. A Lewis dot structure shows an element and its valence electrons. Using Lewis dot structures, we drew the structure of ten different bonds. My group chose 03, BF3, SiCl4, CO, CH2O, SO2, CHCl3, H2S, PH3, and SO3. When drawing the structures of these bonds, we found that finding the right combination of valence electrons was challenging. We had to put valence electrons in areas where each element's structure would be pleased and not only did we have to place them right, but we also had to make sure we had the right amount of electrons as well.
After drawing the bonds, we built them using gumdrops, raisins, and toothpicks. The gumdrops represented atoms, the raisins represented hydrogen, and the toothpicks represented bonds. I was present the first time my group built our structures but we were told that we didn't build them correctly. Unfortunately, I left school while my group corrected them, so all I have is the picture to show for it. The first time we built them, we included too many bonds. After I left my group corrected the molecular structures so that there was the right number of bonds.
During this lab I learned that every molecule has a different structure and way that the valence electrons are displayed. You have to make sure that you place everything according to its blueprints. I also learned how to not only construct molecule structures, but also how to understand how they work.
