In this lab led by Amanda we learned about atoms and valiance electrons and how to draw different kinds of compound elements called Lewis dot structures of the following bonds:
Then we used the knowledge we gained drawing the molecular structure to make 3D diagrams using gum drops, tooth picks, and raisins. The gum drops represented the elements with a corresponding color, the tooth picks connecting the gum drops represented the various bonds between elements, and the raisins represented hydrogen molecules. Once we had a good understanding of the way the bonds connect we made the organic chemical compound diagrams of; caffeine, nicotine, and proline. Many of the simple bonds we used above where included in the organic diagrams which made them a bit easier. These were much more complex but it wasn't too hard to set up the gum drops correctly.
In this lab I gained a better understanding of ionic and covalent compounds and learned what Lewis dot structures are. We learned about how valiance electrons need a full shell of at the most 8 electrons in order to be complete and stable. A Lewis dot structure shows the element and the valiance electrons and how they are bonded together. Another thing I learned is how to look at the periodic table and see how many valiance electrons are in each element. You look at the vertical rows 1-8. I'm beginning to get more used to looking at the periodic table and using it as a tool instead of being intimidated by it. The first thing I did when drawing a Lewis Dot structure was figure out the amount of valiance electrons my drawing had to include. Next I drew the elements that would be incorporated in the drawing. Next I began putting the correct shell of electrons around each element and figuring out weather the element needed a double bond or not.
I know understand that that each molecule has a exact structure and must be displayed with a Lewis Digram with the correct set up of Valiance Electrons. I can conclude that, not only did we have to find the right combination of electrons we also had to be aware of where the electrons are placed because they would effect the bond. Know I also now what a simplified organic structure looks like. That the bonds are all still in the same place but the valiance electrons are not shown but you know that they are there.
